Prop-er volgens mij is dat de Rockwell XFV-12A

Rockwell International's XFV-12A was a supersonic fighter/attack "Thrust Augmenter Wing" concept. The design used a modified 30,000 lb thrust (in afterburner) Pratt & Whitney F401 engine (a larger Navy cousin of the F100 which was canceled before production). For vertical lift, a diverter valve in the engine exhaust system blocked the nozzle and directed the gases through ducts to ejector nozzles in the wings and canards for vertical lift. The thrust of the spanwise ejectors could be modulated by varying the diffuser angle: pitch and roll were controlled by differential variation of the four ejectors from fore to aft and left to right; yaw was controlled by differential ejector vectoring. An auxiliary engine inlet for use in vertical flight was located immediately behind the cockpit. The prototype aircraft used parts from the A-4 and F-4; the fuselage was 44 ft long with a 28.5 ft wingspan and a 12 ft canard span. Operational vertical take-off weight was expected to be 19,500 lb, with a maximum speed of over Mach 2 anticipated by Rockwell. Engine rig testing began testing in 1974, aircraft ground testing in July 1977, and suspended tether trials conducted in 1978. Only one of two contracted aircraft were completed in order to curtail increasing costs. Lab tests were interpreted to show that 55% augmentation could be anticipated, but differences from the lab models to the full scale system caused the actual augmentation to be onlu 19% for the wing and 6% for the canard. Lift improvement testing and plans to modify the ejector/augmentor system were discontinued in 1981 due to cost overruns and waning Navy V/STOL interest.

Dit is een vliegtuig waar er niet veel meer van zijn. Voor zo ver ik weet vliegt er niet één meer. Welk toestel is dit?

Helaas heb ik geen grotere foto.
 
Dat is correct Airbus, het is de Fairy Battle. Ik heb jaren geleden restanten van dit vliegtuig gezien in Duxford. Men was toen aan het uitzoeken of het toestel nog gerestaureerd zou kunnen worden. Nadien heb ik er niets meer van gehoord of gezien.
Het is wel één van de vliegtuigen waar ik ooit nog wel eens een model van zou willen maken. Maar ja, daar zijn er zo veel van. :wink:
Welke foto heb jij voor ons?
 
PIK-26 Mini-Sytky

Airbus probeerde hier een foto van te linken in zijn laatse post:

index.php


Werkt echter niet met die php server, en het linkje verraadt meteen het toestel, daarom beter met Imageshack uploaden ;)




Ik heb het dus ook te makkelijk gevonden en stel dan ook voor dat de eerste willekeurige lezer een nieuw toestel voor ons post! ;)

Fraaie kist, deze kende ik nog niet ;)

Bell XFM-1 Airacuda

'The Bell XFM-1 Airacuda (sometimes called YFM-1) was the first military aircraft produced by the Bell Corporation, and was their answer to the need for a "Destroyer" type aircraft. Thirteen were ultimately produced in two slightly different versions. The first version was a tail dragger with side "blister" ports and a smooth, rounded canaopy. The second version, designated YFM-1A was slightly larger, had more powerful engines, used a tricycle landing gear, smooth side windows, and a rather flattened canopy. Three YFM-1A were produced. The earlier YFM-1 is the better known version and was a bit more appealing design.'

northrop xp79



Northrop chose to construct the aircraft out of a non-critical war material, magnesium. The XP-79 was to be powered by an Aerojet
XCAL-2000 rocket motor capable of propelling the aircraft to 40,000 feet at 538 mph. The XP-79 was to have landing skids. However,
it was later decided to incorporate retractable quadracycle landing gear. The aircraft would have a wingspan of 38 feet and a length
of 13.22 feet. During March 1943, the decision was made to modify the third XP-79 to be powered by two Westinghouse 19-B
axial flow jet engines in place of the Aerojet XCAL-2000 rocket motor. This aircraft would be known as the XP-79B.
On 12 September 1945, the XP-79B, piloted by Harry Crosby, took off for the first time. Two Westinghouse 19-B (J-30) engines
powered the aircraft. After about fifteen minutes of flight, the XP-79B entered what appeared to be a normal slow roll from which it
did not recover and the pilot was killed. With the destruction of the sole XP-79B, the program was canceled.

Moet wel een erg mooi uitzicht gehad hebben. Even zoeken voor de volgende...
 
Vanguard Omniplane

'In February 1959, two former Piasecki engineers formed the Vanguard Air and Marine Corporation to design and build an executive VTOL aircraft. Their first design, the Model 2C Omniplane used a 25 ft long Ercoupe light plane fuselage and weighed 2,600 lb. The round wings each housed a 6 ft diameter three-bladed propeller that was mechanically driven for vertical flight by a 265 hp Lycoming O-540-A1A six cylinder piston engine. During forward flight, covers above the rotors and louvers below sealed the wing for aerodynamic lift. Forward thrust was produced by a 5 ft diameter shrouded propeller in the tail. Elevator and rudder surfaces immediately behind the rear fan controlled pitch and yaw, while differential propeller blade pitch affected roll in hover. Ground tests, starting in August 1959 and including tethered hover trials, were followed by NASA full-scale wind tunnel testing. Modifications to the Omniplane in 1961, including an improved control system, upgrading to a 860 hp Lycoming YT53-L-1 turboshaft engine, and 5 ft nose extension to house a third lifting propeller, led to the redesignation 2D. The nose propeller improved control in pitch as well as in yaw, through the use of movable exit vanes. The 2D completed tethered hover tests, but was damaged by a mechanical failure and discontinued in early 1962.'

Doe dat nou niet....

Straks komt Steffe weer met een vergelijking met één of ander stripboek aan....

:wink: :wink: :wink:
 
Kom er net achter dat dit 'Gyronef' prototype nooit gevlogen heeft :(
