マクドネル・ダグラス(後のボーイング) X-36 テールレス戦闘機敏捷性研究航空機は、ほとんどの航空機で見つかった伝統的な尾のアセンブリなしで飛ぶように設計されたアメリカのステルスサブスケールプロトタイプジェットでした。この構成は、重量、ドラッグ、レーダー断面を減らすが、範囲、操縦性と生存性を増加させるように設計されました。

General Characteristics and Role
The Boeing X-36 Tailless Fighter Agility Research Aircraft was an experimental subscale jet developed by McDonnell Douglas (later Boeing) for NASA and the US Air Force in the mid-1990s. Its primary role was to test the feasibility of a fighter aircraft design that lacked the traditional vertical and horizontal tail surfaces. The X-36 was intended to explore how a tailless configuration could enhance stealth (by reducing radar cross-section) and improve maneuverability, particularly at high angles of attack, compared to conventional fighter jets. It was flown remotely by a pilot in a ground station due to its small size and lack of a cockpit.

Powerplant and Flight Controls
- Engine: 1 x Williams International F112 turbofan engine.
- Thrust: Approx. 3.1 kN (700 lbf).
- Top Speed: Estimated at 370 km/h (230 mph).
- Flight Control System: Required a highly advanced Digital Fly-By-Wire (DFBW) system to maintain stability, as the aircraft was inherently unstable without tail surfaces.
- Control Surfaces: Yaw and pitch control were achieved using canards (foreplanes) and a combination of split ailerons (flaperons) and a thrust-vectoring nozzle on the engine.
Program Outcome and Legacy
- Test Program: The X-36 completed a highly successful test program, demonstrating excellent maneuverability with its tailless design. It achieved a total of 31 flights, logging 15 hours of air time.
- Success Metric: The program demonstrated that a tailless fighter design could achieve up to a 40% increase in cruising lift and a significant improvement in agility over conventional designs.
- Influence: Although the X-36 never led directly to a production aircraft, its successful demonstration of control and stability heavily influenced subsequent low-observable (stealth) aircraft design and DFBW control systems, including possible future unmanned combat air vehicles (UCAVs).
- Preservation: Both X-36 prototypes are now preserved: one is at the National Museum of the United States Air Force in Ohio, and the other is at the NASA Dryden Flight Research Center (now Armstrong) in California.
