USS Carolina del Nord (BB-55) è la nave da battaglia della classe North Carolina e la quarta nave da guerra della Marina degli Stati Uniti ad essere chiamata per lo Stato della Carolina del Nord. Fu la prima nave da battaglia americana di nuova costruzione ad entrare in servizio durante la seconda guerra mondiale e prese parte a tutte le principali offensive navali nel teatro delle operazioni del Pacifico; Le sue 15 stelle di battaglia la resero la corazzata americana più decorata della seconda guerra mondiale.

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.
