Designed in and as a heavy bomber but not meant to be capable of the longer-range missions envisioned for the June 3, dated Bomber A contract winning Heinkel Hethe Do 's design was refined during and production began in late It entered service in early and by the beginning of was available in significant numbers. The Dornier Do had a much larger bomb load capacity and had much greater range than the Do In later variants, dive bombing and maritime strike capabilities using glide bombs were explored in depth, with considerable success in the latter role.
Early Do variants were more powerful than the Heinkel He and Junkers Ju 88having a greater speed, range and bomb load. Owing to this it was designated a heavy bomber rather than a medium bomber. The Do served on all fronts in all roles. On the Eastern Front and Western Front it operated as a strategic bombertorpedo bomber and reconnaissance aircraft. It also performed tactical functions, either direct ground assault or anti-shipping strikes during the Battle of the Atlantic and Battle of Normandy.
The Do was also converted to become a night fighter and saw considerable action in the Defence of the Reich campaign until the last day of the war.
The type also served in anti-shipping units in the Mediterranean, attacking Allied convoys and naval units during the Battle of the Mediterranean. It was in the Mediterranean that the Do became the first aircraft in military aviation history to deploy a form of precision-guided munition in combat, in the form of the Fritz-X radio-guided, free-fall bomb, which led to the sinking of the Italian battleship Roma in After the end of the war, at least one Dornier Do continued in active military operational service with the Swiss Air Force until The Dornier Do The Do was to be a larger, improved version in all areas.
At the beginning ofDornier issued manufacturing specification No. For smoke-laying, the aircraft could be fitted with two Type S smoke generators. Dornier also envisaged the Do as a naval dive bomberin which case it was to be fitted with twin floats. The wing span was to be slightly larger than the Dornier Do 17 by one metre. Under the wing a retractable diving air brake was to be installed. On 5 June Dornier's overview of its design submitted to the Technical Bureau Technisches Amt highlighted some structural differences with the Do The fuselage was to be not only bigger but also structurally stronger.
The RLM also had other requirements for Dornier to fill. In January the Naval Air Arm Inspectorate of the Luftwaffe presented its requirements for a multi-purpose twin-engined all-metal aircraft that could also conduct maritime operations. On 5 February it was agreed with the General Staffwhich had said up until that point, the naval air attack capability of German air units was poor in multi-engine bomber units. The results were a two percent hit rate.
The superior hit rate of aircraft with dive bombing capabilities was clear. The Luftwaffe also wanted a machine that could operate as a fighter aircraft to combat enemy aircraft. Essentially they wanted a "sea Stuka " Junkers Ju Dornier set about designing a Dornier floatplane. For hitting targets in the air and sea surface, four machine guns would be fitted in the nose.The electronic journal of combinatorics
The armament would consist of two MG 17 machine guns rounds of ammunition each and two MG machine guns rounds of ammunition as part of the Dornier Do P. Defensive armament was to consist of MG 15s to cover the aft approach. The tail was to consist of the same twin stabilizer configuration as the Doalthough a single fin was planned.
For dive bombing capability a dive brake was installed underneath the wing, like the Ju The power plants were to reflect the speed requirements.
The specifications were dated 8 March At this point, the Ju 88 and He equipped units were ordered to cease providing maritime support en masse.In the 20s and 30s of last century, the firm Dornier was the leading one in German flying boat construction. Normally the Wal was a two engined machine, and so were its successors Do 15 and Do With prospected increase of Atlantic traffic, Dornier renewed this configuration for another type, the Do The new flying boat became a special aerodynamic beauty.
The wing stubs were omitted, and stabilizer floats retractable to the wings were foreseen instead. In the position of the bend of the gull wing, the machine carried the four Jumo C Diesel engines, delivering hp each.Juicy j promethazine
The aircraft was an all-metal construction. But the civil career of the Do 26 remained short.
Dornier Do S
Although the Boeing was already serviceable in Mayso there have been no fair economic reasons, the USA refused to permit a regular service route over the North Atlantic between Lisbon and New York for the Do Because of this, the Do 26 only operated on the South Atlantic route. Two Passengers could be carried alongside to the mail, one time even three. After their return, they received a military equipment, including a 20 mm cannon in a rotating turret on the bow and some machine guns in blister-formed glazed stations on both sides of the fuselage right behind the wing.
Four more samples were built, now under the designation Do 26 C, what meant receiving military equipment from the beginning together with Jumo D engines of hp performance.
But they soon had to suffer heavy losses. The aircraft were strafed on the ground and sunk. One wreck in comparably good condition was found in The qualities of the Dornier Do 26 suggested use as long-range reconnoiter. In fact, they were the only German aircraft at that time, besides the Focke-Wulf FWcapable to perform such actions at all.
On 31 Julytwo Do 26 were stationed at Brest to do reconnaissance for the German U-Boat operations, since convoys supplying Britain now used the northern approach. The third one followed some time later. Until 30 September, the Do 26s flew 17 sorties on 12 days.It was produced by Claudius Dornier 's company, Dornier Flugzeugwerke. The aircraft was designed as a Schnellbomber "fast bomber"a light bomber which, in theory, would be so fast that it could outrun defending fighter aircraft.
The Dornier was designed with two engines mounted on a " shoulder wing " structure and possessed a twin tail fin configuration.Top 10 Biggest / Largest RC Airplanes In The World [VIDEOS]
The type was popular among its crews due to its handling, especially at low altitude, which made the Do 17 harder to hit than other German bombers. Designed in the early s, it was one of the three main Luftwaffe bomber types used in the first three years of the war. The Do 17 made its combat debut in during the Spanish Civil Waroperating in the Condor Legion in various roles. Along with the Heinkel He it was the main bomber type of the German air arm in — The Dornier was used throughout the early war, and saw action in significant numbers in every major campaign theatre as a front line aircraft until the end ofwhen its effectiveness and usage was curtailed as its bomb load and range were limited.
Production of the Dornier ended in mid, in favour of the newer and more powerful Junkers Ju The successor of the Do 17 was the much more powerful Dornier Dowhich started to appear in strength in Even so, the Do 17 continued service in the Luftwaffe in various roles until the end of the war, as a glider tug, research and trainer aircraft.
A considerable number of surviving examples were sent to other Axis nations as well as countries like Finland. Few Dornier Do 17s survived the war and the last was scrapped in Finland in On 10 Junethe salvage team raised the airframe from the seabed. Inthe Ordnance Department Heereswaffenamt issued a specification for the construction of a "freight aircraft for German State Railways ", and a "high speed mail plane for Lufthansa ".
The Ministry of Aviation designated the new aircraft Do 17and on 17 Marchjust three months after taking office, Milch gave the go ahead for the building of prototypes. At the end ofthe Ministry of Aviation issued an order for a "high speed aircraft with double tail," and for a "freight aircraft with special equipment," in other words, a bomber.
The original design the Do 17 V1 configuration in had sported a single vertical stabilizerand Dornier continued developing that model. The Do 17 was first demonstrated in mock-up form in April The "special equipment" was to be fitted later, to disguise its offensive role.
In Aprilthe Dornier works at Manzell began project "definition. Testing was delayed by a series of accidents, with V1 being damaged in landing accidents in February and April First conceived by Dr. Claudius Dornier inplanning started in late Construction work started on 19 December and the Do X was completed in Juneafter overwork hours.
Launched on 12 Julythe Do X immediately began taxiing trials. These soon led to flights conducted over the following six months, during which time the aircraft was briefly grounded, to allow replacement of the original Bristol Jupiter engines by Curtiss Conquerors.

The Dornier Do X was the largest, heaviest, and most powerful flying boat in the world when it was produced by the Dornier company of Germany in The Do X was financed by the German Transport Ministry and built in a specially designed plant at Altenrhein, on the Swiss portion of Lake Constance, in order to circumvent the Treaty of Versailles which forbade any aircraft exceeding set speed and range limits to be built in Germany after World War I.
While the type was popular with the public, a lack of commercial interest and a number of non-fatal accidents prevented more than three examples from being built. History Edit First conceived by Dr. Midsummer Books Ltd. Categories :.
Cancel Save.The Pfeil ' s performance was much better than other twin-engine designs due to its unique push-pull configuration and the lower aerodynamic drag of the in-line alignment of the two engines.
The origins of the Do trace back to World War I when Claude Dornier designed a number of flying boats featuring remotely driven propellers and later, due to problems with the drive shafts, tandem engines. Tandem engines were used on most of the multi-engine Dornier flying boats that followed, including the highly successful Do J Wal and the gigantic Do X.
The remote propeller drive, intended to eliminate parasitic drag from the engine entirely, was tried in the innovative but unsuccessful Do 14and elongated, tubular drive shafts as later used in the Do saw use in the rear engines of the four-engined, twinned tandem-layout Do 26 flying boat.
There are many advantages to this design over the more traditional system of placing one engine on each wing, the most important being power from two engines with the frontal area and thus drag of a single-engine design, allowing for higher performance. It also keeps the weight of the twin powerplants near, or on, the aircraft centerline, increasing the roll rate compared to a traditional twin.
In addition, a single engine failure does not lead to asymmetric thrustand in normal flight there is no net torque, so the plane is easy to handle. The four-surface set of cruciform tail surfaces in the Do 's rear fuselage design included a ventral vertical fin — rudder assembly to project downwards from the extreme rear of the fuselagein order to protect the rear propeller from an accidental ground strike on takeoff.
The presence of the rear pusher propeller also mandated the provision for an ejection seat for safe escape from a damaged aircraft, and designing the rear propeller and dorsal fin mounts to use explosive bolts to jettison them before an ejection was attempted — as well as twin canopy jettison levers, one per side  located to either side of the forward cockpit interior just below the sills of the five-panel windscreen's sides, to jettison the canopy from atop the cockpit before ejection.
Dornier Do 217
InDornier was busy working on the P. The P. In autumnDornier was told that the Do was no longer required, and instead a multi-role fighter based on the same general layout would be accepted. This delayed the prototype delivery as it was modified for the new role.
Dornier Do X
The use of a nose-mount annular radiator for the forward engine much like a Jumo -powered Ju 88or Jumo -powered Focke-Wulf Fw D-9 and a ventral-fuselage mount airscooped radiator installation for cooling the rear engine appearing like that on a P Mustang was distinctive. However, several problems during the initial flight of the Do would continue to plague the aircraft through most of its short history.
Issues were found with the weak landing gear and with the main gear's wheel well doors, resulting in them being removed for the remainder of the V1's test flights. The Do V1 made 27 flights, flown by three different pilots. During these test flights the V2 W. New to the V2 were upgraded DB A-2 engines, and several refinements learned from the test flights of the V1 as well as further windtunnel testing. On 20 Januarythe Do V3 W. By this time, more than 60 hours of flight time had been put on the Do and reports showed it to be a good handling, but more importantly, very fast aircraft, described by Generalfeldmarschall Erhard Milch himself as " Thus the Do was scheduled to begin mass construction, with the initial order of preproduction aircraft to be manufactured by DWF Dornier-Werke Friedrichshafen to be completed no later than March This number included a number of bombers, destroyers heavy fightersand several yet to be developed variants.
The main production line was intended to be at Manzell, but a bombing raid in March destroyed the tooling and forced Dornier to set up a new line at Oberpfaffenhofen. The decision was made, along with the rapid shut-down of many other military aircraft development programs, to cancel the Heinkel He night fighterwhich also used the DB engines in well- unitized installationsand use its production facilities for the Do as well. However, Ernst Heinkel managed to delay, and eventually ignore, its implementation, continuing to produce examples of the He A.
At least 16 prototype Do s were known to have flown V1—V12, W. Nr and Muster -series prototypes M13—M17, W. The first preproduction Do A-0s starting with W. Approximately 22 preproduction aircraft were thought to have been completed and flown before the end of the war, including approximately 11 A-0s converted to As for training purposes.
One such aircraft was transferred to the Royal Aircraft Establishment in Farnboroughand later, after a rear-engine fire burnt through the elevator controls during a flight, crashed onto a local school. The first 10 Do A-0 s were delivered for testing in May. By latethe Do A-1 was on the production line. Delivery commenced in January When the United States Army overran the Oberpfaffenhofen factory in late Aprilonly 11 Do A-1 single-seat fighter-bombers and two Do A trainers had been completed.
He describes leading a flight of four Hawker Tempests from No. Detecting the British aircraft, the German pilot reversed course to evade.The Dornier Do S was a large, passenger flying boat airliner flown in Germany in Only one was built. The all-metal Dornier Do S was intended to replace the Dornier Do R 4 Superwala four-engined, passenger flying boat flown four years earlier. The main wing of the Dornier S was in three parts, with a central panel attached to the crew's compartment on top of the main fuselageand two outer panels.
It was rectangular in plan, with a chord of 8. The wing was built around three duralumin trellis sparswith dural ribs and skin. The inner panel was supported by two vertical struts from the sponsons.
On each side the main outer bracing was provided by a single strut from the inner sponson to the central spar of the outer panel, at about half-span. These were assisted by steel flying wires from below, between the forward and rear spars and the sponsons, and from above by a single wire from the raised engine mountings and their cross-bracing auxiliary wing, to the forward spar.
High aspect ratio ailerons occupied all the trailing edge of the outer panels, aerodynamically balanced by small auxiliary surfaces mounted forward and well above the hinge line.
The lower part of the fuselage followed Dornier's usual practice, with a narrow-V cross-section forward changing to a flat bottom, with a deeper centre region, near the single step and a V-section aft ending with a water rudder. There were two passenger cabins, one seating twelve forward of a lobby accessed by a starboard side door and containing a cloakroom, toilet, library and medicine cabinet. Behind it was a second passenger compartment for ten, with a kitchen aft.
At the stern the empennage was conventional, with a fin that had a swept leading edge and blunted top, carrying a rudder which reached down to the top of the fuselage.
Its tailplanewith a plan similar to that of the wing, was braced from below by a pair of parallel struts on each side and was adjustable in flight. It carried elevators which were aerodynamically balanced in the same way as the ailerons.
The crew were housed in a separate structure above the cabin which also formed the central connection between wing and fuselage. It began well forward of the leading edge and ended just aft of the trailing edge.Ania
The pilot's open cockpit near the front had a pair of side-by-side seats with dual controls. Further aft, there were positions for a flight engineer, a navigator and a radio operator, one of whom could act as co-pilot.
Each engine in a pair had a radiator occupying half the front of the rectangular section nacelle. Each pair was mounted on two V-struts and two wider-spread inverted V-struts to the forward and central spars. The upper engine mountings were braced together centrally by a narrow-chord structure which acted as an auxiliary wing as well as being part of the main wing bracing structure.
The Do S's first flight was made on 23 September from the Bodensee. Data from Les Ailes, January . From Wikipedia, the free encyclopedia. Les Ailes : 3.Brodo di pollo e verdure 10 x 5g in mellin
