    The conceptual design featured a large tandem wing aircraft with V-22 type engines and 50-foot (15 m) rotors at each of the four wing tips. The C-130-size fuselage would have a 747-inch (19.0 m) cargo bay with a rear loading ramp that could carry 110 paratroopers or 150 standard-seating passengers.

    en.wikipedia.org/wiki/Quadcopter

    A quadcopter, also called quadrocopter, or quadrotor [1] is a type of helicopter or multicopter that has four rotors. [ 2 ] Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern unmanned aerial vehicle or drone.

    In 1974, the company eliminated the 2-cycle engine and, unable to find a manufacturer to make their 4-cycle engine suitable for the helicopter, began production of their own engine. This engine, called the RotorWay RW133 , was a 4-cycle engine that was able to provide a cruise speed of 80 mph (130 km/h) with a range of 120 miles (193 km) and a ...

    The General Electric T64 is a free-turbine turboshaft engine that was originally developed for use on helicopters, but which was later used on fixed-wing aircraft as well. General Electric introduced the engine in 1964. The original engine design included technical innovations such as corrosion resistant and high-temperature coatings. [1]

  8. Tiltwing - Wikipedia

    en.wikipedia.org/wiki/Tiltwing

    Tiltrotors generally have better hover efficiency than tiltwings, but less than helicopters. [4] This is due to the difference in rotor disk loading. As of 2014, NASA is testing a diesel-electric hybrid 10-foot 10-rotor tiltwing called the GL-10 Greased Lightning , with most propellers folding during horizontal flight.
