Cargo capacities provided reflect the airframe manufacturer's specifications; when put into practice the actual maximum load capacities may be less, depending on the rating of the cargo hook equipment. For example, if a helicopter model is rated by the manufacturer as having a maximum cargo sling load capacity of 4,000 lb, but the cargo hook ...
The U.S. Department of Transportation has published a “Basic Helicopter Handbook”. One of the chapters in it is titled, “Some Hazards of Helicopter Flight'. Ten hazards have been listed to indicate what a typical single rotor helicopter has to deal with. The coaxial rotor design either reduces or completely eliminates many of these hazards.
A Bell XH-40, a prototype of the UH-1 and Bell 204. Bell designed its Model 204 in response to a 1955 United States Army requirement for a utility helicopter. The 204 was a giant step forward in helicopter design, being one of the first to be powered by a turboshaft.
With the Rotax 912ULS engine, the gross weight is 500 kg (1,102 lb), 550 kg (1,213 lb) with the Rotax 912ULS-1 and 600 kg (1,323 lb) with the Rotax 914. [1] [2] The aircraft fuselage frame is made from welded stainless steel tubing. Its two-bladed rotor has a diameter of 7.14 m (23.4 ft) and a chord of 18.5 cm (7.3 in).
This category is intended for equipment that is associated specifically with the operation of helicopters but is not a component of the helicopter required for the function of flight (e.g. rotors, engines, controls).
The Piasecki PV-3 was adopted as the HRP-1 Rescuer by the United States Navy, United States Marine Corps, and United States Coast Guard. [1] An improved PV-17 variant was later produced as the HRP-2. As one of the first transport helicopters in military service, the HRP-1 was capable of carrying two crewmen and 8–10 passengers or 2,000 lb ...
A typical helicopter has three flight control inputs: the cyclic stick, the collective lever, and the anti-torque pedals. [2] Depending on the complexity of the helicopter, the cyclic and collective may be linked together by a mixing unit , a mechanical or hydraulic device that combines the inputs from both and then sends along the "mixed ...
The HTT-40 is a tandem seat trainer aircraft powered by a 1,100 hp (820 kW) turboprop engine. In early 2012, the company forecast building 106 examples. [5]By the middle of 2012 the aircraft's future was in doubt as the Indian Air Force ordered 75 Pilatus PC-7 Mk IIs to fill the role envisioned for the HTT-40.
