[37][38], Several CG rendered views of Have Blue, with overhead comparison of size relative to the F-117, Data from Crickmore,[39] Donald,[2] Aronstein and Piccirillo[40], Quote: "The results of these studies were sufficiently promising that the Air Force issued a development contract on 16 November 1977 under the name. The aircraft was disassembled, loaded onto a C-5, and on 16 November, the aircraft was flown from Burbank Airport (since renamed Bob Hope Airport) to Area 51 at Groom Lake, Nevada. [32], HB1001 made its first flight on 1 December 1977 at the hands of Lockheed test pilot, Bill Park. [4] If the loss ratio of Israel during the Yom Kippur War was experienced by NATO forces during a military confrontation with the Warsaw Pact, NATO aircraft numbers would be depleted within two weeks. Phase 2 encompassed three main objectives, which were the validation of: reduced visibility in the radio wave, infrared, and visual spectrums and reduced acoustical observability; acceptable flying qualities; and the "modeling capabilities that accurately predict low observable characteristics of an aircraft in flight".

I said "Well, it's simple, you just make it out of flat surfaces, and tilt those flat surfaces over, sweeping the edges away from the radar view angle, and that way you basically cause the energy to reflect away from the radar. Spotlighting lets you share this airplane with all of your followers. In early November, two semi-trailers were parked parallel to each other outside Building 82; a camouflage net was thrown over the top to cover the demonstrator during outdoor engine runs. If the loss ratio of Israel during the Yom Kippur War was experienced by NATO forces during a military confrontation with the Warsaw Pact, NATO aircraft numbers would be depleted within two weeks. The Have Blue was the first fixed-wing aircraft whose external shape was defined by radar engineering rather than by aerospace engineering. -AG4 and STOVL down opens bomb bay. Item kan niet op de lijst worden gezet. A hydraulic leak caused an engine fire, resulting in the loss of hydraulic pressure, which in turn caused severe pitch oscillations. Lockheed Have Blue was the code name for Lockheed's demonstrator (i.e., "proof of concept") that preceded the F-117 Nighthawk production stealth aircraft. Prototype engines were installed in the two competing technology demonstrator aircraft, the Lockheed YF-22 and Northrop YF-23. The scheme, consisting of three colors, each with three tones, was used to deceive any casual onlooker from recognizing the design's characteristic faceting. As a result, General Dynamics left the discussion. [33] Flight test results allowed engineers to refine the FBW system. [27] After four taxi tests, HB1001 was ready for test flights. The pilot ejected safely, and the aircraft was destroyed. The front fuselage was shortened to give the pilot a better view, and the vertical stabilizers were canted outwards from the centerline. Final assembly of HB1001 was originally scheduled to be completed in August 1977, before being ground tested until mid-October. [23] HB1001 received a layer of iron-coat paint; during the weekend of 12–13 November, the aircraft received a camouflage scheme devised by Alan Brown, Have Blue's chief technical engineer. The design effort produced a number of wooden models. Designed by Lockheed’s Skunk Works division, and tested at Groom Lake, Nevada, the Have Blue was the first fixed-wing aircraft made from an electrical engineering (rather than an aerospace engineering) perspective. The company used "GENSCAT", software similar to ECHO 1, to calculate the RCS of its designs. In the 1970s, it became increasingly apparent to U.S. planners that, in a military confrontation with Warsaw Pact forces, NATO aircraft would quickly suffer heavy losses. [36] The Tactical Air Command ordered five full-scale development and twenty production aircraft. Flight instrumentation was checked first, followed by a thorough shakedown of the aircraft. Upon touchdown, the aircraft was reassembled before undergoing another round of testing prior to the first flight. The design was a finalist in the USAF's Advanced Tactical Fighter competition, and two prototypes were built for the demonstration/validation phase of the competition. In the event, the aircraft's RCS level confirmed ECHO 1's predictions.

Tactical Air Command ordered five full-scale development and twenty production aircraft. Keep up the good work with these planes man! In March 1976, a Lockheed model was transferred to the range before being tested; the following month Lockheed was pronounced the winner. [7] In 1964, Pyotr Ufimtsev, the chief scientist of the Moscow Institute for Radio Engineering, published a seminal paper titled Method of Edge Waves in the Physical Theory of Diffraction. The Lockheed Have Blue was a proof of concept aircraft for stealth. The aircraft pitched up just as it made contact with the ground which forced the pilot, Bill Park, to abort the landing and make a second attempt. The aircraft's faceted shape was designed to deflect electromagnetic waves in directions other than that of the originating radar emitter, greatly reducing its radar cross-section. He [Park] raised the gear on the go around, and when he tried to extend it on approach, only one of the mains and the nose wheel came down. The company used "GENSCAT", software similar to ECHO 1, to calculate the RCS of its designs. In early November, two semi-trailers were parked parallel to each other outside Building 82; a camouflage net was thrown over the top to cover the demonstrator during outdoor engine runs. [18] He made his first flight on HB1001 on 17 January 1978, chased by Park.

Following Phase 1, a sole contractor would be selected to continue with the construction and flight testing of two demonstrators as part of Phase 2. Efforts to lower the gear were unsuccessful and Bill Park was forced to climb again, and eject when his fuel ran out. [37] The first production F-117A was delivered in 1982, and operational capability was achieved in October 1983; the 59th and last F-117A was delivered in 1990. [33], Based on the Have Blue demonstrators, Senior Trend aircraft were different from their predecessors in several aspects. [32] HB1002 was distinguished from the prototype in having a gray paint coat. A group of managers took over the job of assembly, which was completed in six weeks, with ground tests beginning on 17 October. Lockheed Have Blue has been listed as one of the Warfare good articles under the good article criteria.If you can improve it further, please do so. This came as a result of sophisticated Soviet defense networks, which used surveillance radars and radar-guided surface-to-air missiles (SAM) and anti-aircraft artillery to seek and eliminate enemy aircraft. Rich won the argument with Johnson, a rare occurrence. The Lockheed Have Blue was born out of a requirement to evade radar detection. Sorry, er is een probleem opgetreden bij het opslaan van je cookievoorkeuren. The second point was whether these companies had the capacity to design and manufacture such an aircraft. As the aircraft was used to test RCS returns, the unstealthy spin recovery chute was removed, and the aircraft was covered in RAM.
