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.
A PW4074 engine had a fan blade failure and associated engine cowl damage as the Boeing 777-200 was climbing out of Okinawa. [18] As of March 2021 the investigation is ongoing. 20 February 2021, United Airlines Flight 328 Boeing 777-200's right hand PW4077-112 had a blade failure shortly after taking off from Denver, causing significant engine ...
The PW1500G variant, designed for the Airbus A220, became the first certified engine in 2013. The program cost is estimated at $10 billion. Unlike traditional turbofan engines where a single shaft connects all components, forcing them to operate at the same speed, the PW1000G has a gearbox between the fan and the low-pressure core. This allows ...
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 2,500 lbf (11 kN) thrust PW625F demonstrator engine was first run on 31 October 2001. [1] It flew in late 2002. [2] In 2002, the PW610F was selected for the Eclipse 500 twinjet, replacing the EJ22 as Williams was unable to reach sufficient reliability. The 950 lbf (4.2 kN) thrust engine was certified by Transport Canada on 27 July 2006. [3]
The CoAX 2D/2R was originally known as the FLIP 2 (Fly In Perfection) and is a derivative of the FLIP 1, a conventional helicopter with a main and tail rotor.[1]The CoAX 2D/2R was designed to comply with the European Class 6 microlight helicopter rules, including the category's maximum takeoff weight of 450 kg (992 lb).
The engine contains an in-flight engine condition monitoring system (IECMS) that monitors for critical malfunctions and keeps track of parts lifetimes. [ 3 ] GE developed the F110 for the Air Force as an alternative to the Pratt & Whitney F100 for use on the F-16 and F-15 based on the F101 and used F404 technology. [ 4 ]
Turboshaft engine with a maximum and normal power rating of 2,200 and 1,850 shp (1,640 and 1,380 kW) and a pressure ratio of 6:1; high-speed version of the T55-L-3 [21] allowed for use on the Chinook instead of the geared YT55-L-3 engine due to August 1958 engine contract modification, with the reduction gearing now provided in the helicopter ...
