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.
Engines with a future planned block 4 upgrade would be expected to deliver nearly 10,000 horsepower (7,500 kilowatts). [ 19 ] An ongoing problem with the engines was their propensity for surging or stalling with 68 incidents reported between 2003 and October 2016 though this rate had reduced after the introduction of the Block 3 engine version.

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.
The higher the loading, the more power needed to maintain rotor speed. [3] A low disk loading is a direct indicator of high lift thrust efficiency. [4] Increasing the weight of a helicopter increases disk loading. For a given weight, a helicopter with shorter rotors will have higher disk loading, and will require more engine power to hover.
It later flew up to 1.52 m (4.99 ft) above the ground. The design was improved and the Gyroplane No.II appeared the following year. No.II had two two-blade rotors of 7.85 m (25.75 ft) diameter and also had fixed wings. Powered by a 41 kW (55 hp) Renault engine, it was reported to
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 Kawasaki KH-4 was a light utility helicopter produced in Japan in the 1960s as a development of the Bell 47 that Kawasaki had been building under licence since 1952. The most visible difference between the KH-4 and its forerunner was its new and enlarged cabin .
