Разработка, комплексирование и летные испытания автоматической системы предотвращения столкновений с Землей

Abstract

Much work has been accomplished over the past 20 years in the developing and testing of an Auto GCAS. In the past three years, a Fighter Risk Reduction Pro- gram (FRRP) has been undertaken by the Air Force Research Laboratory (AFRL) at Wright Patterson AFB. This program is a joint effort between AFRL, NASA Dryden, Lockheed Martin Aeronautics, and the Air Force Flight Tests Center. The FRRP has advanced Auto GCAS technology to a level now capable of production transition. Results of this effort will be discussed in this paper. The F-16 test air- craft is shown in Fig. 1. Controlled Flight Into Terrain (CFIT) is defined as collision with terrain, water, trees or a man-made obstacle during flight prior to planned touchdown. CFIT includes mishaps where the aircraft is controllable and the pilot is actively control- ling the aircraft or the pilot’s ability to control the aircraft is reduced due to spatial disorientation. CFIT also includes mishaps where the aircraft is flown in con- trolled flight to a point where it is no longer possible to avoid unintended ground impact (e.g., attempted maneuver with insufficient altitude or airspeed, low altitude over bank or flight into a box canyon), regardless of subsequent pilot reaction (e.g., add power, maneuver to avoid terrain, etc.). Prevention of CFIT mishaps utilizing Auto GCAS will be presented. The requirements for Auto GCAS and the order of importance of those requirements will be discussed in this paper.
