At the same time, they verified predictions made earlier by aerodynamic engineers on the aircraft's behavior. I suggested he climb up to 10, feet for ejection The heat built up there, causing the hydraulic lines to fail. And, the vertical stabilizers were canted outwards from the centerline. Origins[ edit ] The Lockheed Have Blue was born out of a requirement to evade radar detection. In fact, the two would be the only test pilots of Have Blue, alternating between the demonstrator and the chase plane. The first was about the signature thresholds at which an aircraft is virtually undetectable.

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. A hydraulic leak caused an engine fire, resulting in the loss of hydraulic pressure , which in turn caused severe pitch oscillations. US Air Force , public domain While several Stealth Fighters have been sighted back in the air over Nevada, most of the retired fleet rests semi-dismanted in their original hangars at Tonopah. As a result, General Dynamics left the discussion. Further problems, this time with fuel leaks, delayed the first flight. 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. The pilot ejected safely, and the aircraft was destroyed. The impact had however been so hard that the landing gear had become jammed in a semi-retracted position. Phase 2 encompassed three main objectives, which were the validation of: Efforts to lower the gear were unsuccessful and Bill Park was forced to climb again, and eject when his fuel ran out. 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. At the same time, they verified predictions made earlier by aerodynamic engineers on the aircraft's behavior. The flight control system was borrowed from the F Overholser later recounted his discussion with Sherrer: Johnson advocated for the use of blended shapes as the best way to achieve stealth, while Ben Rich advocated for faceted angles. The front fuselage was shortened to give the pilot a better view. As such, strike aircraft during the war often required support aircraft to perform combat air patrols and suppression of enemy air defenses SEAD. 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. The second point was whether these companies had the capability to design and manufacture such an aircraft. It did not have the flight test instrumentation boom present on HB's nose. During the engine tests, a local resident complained about the noise, but Have Blue retained its secrecy. All this time, gas was being consumed It seemed it slammed down on the ground real hard In fact, the two would be the only test pilots of Have Blue, alternating between the demonstrator and the chase plane. Engineers later encountered the same difficulty fabricating the prototype on the factory floor.
