Можда је било на теми о Ф-16, али како је не пратим...
Citat:In 1976, DARPA (Defense Advanced Research Projects Agency) awarded funds to General Dynamics, Rockwell and Grumman under the Forward-Swept Wing Program. Forward-swept wings offer low drag and improved low-speed handling characteristics, but they are extremely difficult to manufacture using conventional techniques. The use of advanced composite materials makes the wing rigid enough to withstand the forces introduced by aerodynamic stress, while simultaneously avoiding a weight penalty.
The SFW/F-16 never left the drawing board.
The engineers at General Dynamics studied several designs, including one with canards and an aft-mounted wing. The final design submitted to DARPA used the landing gear and most fuselage components of the traditional F-16, yet it had a slightly lengthened and strengthened fuselage to allow the forward-swept wing to be attached, since the new wing was slightly larger than the traditional wing.
The SFW/F-16 was rejected by DARPA in January of 1981 in favor of the Grumman 712 (an F-5/F-20 derivative), later designated the X-29A...
Citat:Lockheed Swing Wing Design
CL-507 was a Lockheed preliminary design effort in 1960 that involved a series of STOVL and VTOL fighter bombers with maximum speeds in the Mach 2 range. This variation (507-27) had variable-sweep wings.
Grumman Design 128G-12, предлог морнаричког лаког јуришног једноседа заснованог на А-6, а који је требало да замени А-4...Citat:When BuWeps (US Navy Bureau of Naval Weapons) requested proposals for the VA(L) light attack aircraft in June 1963, it specified that manufacturers should only submit designs which were minimum change modifications of existing designs as low cost and early availability were of prime importance. Accordingly, in August 1963 Grumman submitted its Design 128G-12, a derivative of the A-6A. As the VA(L) was intended for day operations in clear weather, the complex integrated navigation and bombing system of the A-6A was replaced by a simpler multimode radar, and a single-seat-on-centreline cockpit was substituted for the two-seat cockpit of the A-6A. The only other significant change was the incorporation of a folding horizontal tail to increase by one third the carrier spotting factor. The Navy finally selected the smaller lighter LTV proposal even though the resulting A-7A had much less commonality with the F-8. http://www.angelfire.com/space/grumman/aircraft/designs.html
In 1974, the US Navy issued a request for proposals for a lightweight multi-role aircraft that could serve as both a fighter and as an attack aircraft. The aim was to replace both the F-4 Phantom II an the A-7 Corsair II with an aircraft that had a lower cost than either the F-14 or the F-111.
Convair reacted by a proposal of the F/A-201 Kestrel. It was based on an earlier proposal for an ‘Advanced F-106’ and was designed with a single Pratt & Whitney JTF22A-30A/F100-PW-220 engine.
The Kestrel was to have a delta/canard wing configuration. There were to be both land-based and carrier-based aircraft. Convair also proposed to produce a V/STOL version with two lift fans and a vectoring nozzle on the main engine. The aircraft was designed with a fly-by-wire control system.
In 1975 the U.S. Navy decided to select a derivative of the YF-17, the loser of the U.S: Air Force Lightweight Fighter (LWF) Aircraft competition which resulted in the F-16. The YF-17 was converted into the F/A-18 Hornet and the Kestrel proposal never went beyond the model stage. https://www.facebook.com/photo.php?fbid=1020627545.....mp;theater
Skywhaler :: Citat:The Hawker P.1121 was an unbuilt British design for a supersonic fighter aircraft. The design was to be powered by either the de Havilland Gyron, Bristol Olympus or Rolls-Royce Conway engines, it was designed by a team headed by Sydney Camm and funded as a company project to meet an Air Ministry Operational Requirement (OR.339). Work was stopped in 1958,[1] after the infamous 1957 Defence White Paper by Minister of Defence Duncan Sandys, which called for manned fighter aircraft to be phased out and replaced with guided missiles. https://en.wikipedia.org/wiki/Hawker_P.1121
Stvarno mi nije jasno kako je stopiran ovaj projekat
Citat:The final and most spectacular redesign was a Mach 2 variable geometry ("swing wing") machine, the Folland "Fo.148", that was intended as a trainer, air superiority fighter, or light strike aircraft. The wings were to have full-span leading-edge flaps and slotted trailing edge flaps; there would be a single stores pylon on each side of the fuselage. It was to have been fitted with an afterburning RB.153 engine with a thrust reverser. The Fo.148 was said to have been the last aircraft design to bear a Folland designation before the company was absorbed into the Hawker-Siddely group. It was an interesting design and it is a bit of shame it never flew.
