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.
The QTR is a larger, four rotor version of the V-22 with two tandem wings sets of fixed wings and four tilting rotors. In January 2013, the FAA defined US tiltrotor noise rules to comply with ICAO rules. A noise certification will cost $588,000, same as for a large helicopter. [15] [16]
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.
The kit was designed specifically for the Rotorway Exec, to convert it to turbine power, under the US Experimental - Amateur-built aircraft rules. The resulting aircraft features a single main rotor, a two-seats-in side-by-side configuration enclosed cockpit with a windshield, skid-type landing gear and a 150 hp (112 kW) Solar T62 turbo-shaft engine.
The Bell 214ST has a larger, stretched fuselage with seating for 16-18 passengers, [10] [11] and two 1,625 shp (1,212 kW) GE CT7-2A engines. [12] The helicopter introduced some ground-breaking innovations for Bell, including a one-hour run-dry transmission, fiberglass rotor blades, elastomeric rotorhead bearings, and the option of either skid ...

The initial production aircraft being powered by a pair of General Electric T58-GE-8B turboshaft engines, each capable of providing up to 930 kW (1,250 shp). [4] Sikorsky quickly decided to pursue development of a dedicated commercial model of the Sea King. [1] In fact, two prime models were produced: the land-based S-61L and the amphibious S ...
