Aircraft of low observability

摘要: An aircraft which has a very low observability visually and to radar, thel acoustic detecting devices. The is designed have as few edges surfaces possible, such delta wing type, the being straight, or near straight vertices rounded. All are flat within limits of aerodynamic requirements, entire surface electrically conductive with minimum discontinuity. propulsion unit faired into shielded from radar by wing. Portions aircraft, particularly edges, may be absorbing material, any essential openings, ducts protruding fins similarly minimize cross section.
