The Pratt & Whitney PW2000, also known by the military designation F117 and initially referred to as the JT10D, is a series of high-bypass turbofan aircraft engines with a thrust range from 37,000 to 43,000 lbf (160 to 190 kN).
It is built around an 0.72 scale of the GE90-110B/115B core [1] and contains a Pratt & Whitney fan and low-pressure system design. The competing Rolls-Royce Trent 900 was named as the lead engine for the then-named A3XX in 1996 and was initially selected by almost all A380 customers.
front cover G1 1930. This is the Group G series List of the United States military vehicles by (Ordnance) supply catalog designation, – one of the alpha-numeric "standard nomenclature lists" (SNL) that were part of the overall list of the United States Army weapons by supply catalog designation, a supply catalog that was used by the United States Army Ordnance Department / Ordnance Corps as ...
When the optimum speed is reached, i.e. the flow of gas through the turbine is sufficient, the turbines take over. There are a number of different starting methods such as electric, hydraulic, pneumatic, etc. The electric starter works with gears and clutch plate linking the motor and the engine.
The sequence of events is similar for manual or automatic synchronization. The generator is brought up to approximate synchronous speed by supplying more energy to its shaft - for example, opening the valves on a steam turbine, opening the gates on a hydraulic turbine, or increasing the fuel rack setting on a diesel engine. The field of the ...
Because the magneto has low voltage output at low speed, starting an engine is more difficult. [5] Therefore, some magnetos have an impulse coupling, a spring-like mechanical linkage between the engine and magneto drive shaft which "winds up" and "lets go" at the proper moment for spinning the magneto shaft.
Klimov TV3-117 turboshaft engine. The accessory drive is the large casting on the top. The accessory drive is a gearbox that forms part of a gas turbine engine. [1] Although not part of the engine's core, it drives the accessories – such as generators, pumps for fuel and lubrication oil, air compressors, hydraulic pumps and engine starters – that are otherwise essential for the operation ...
This is a list of auto parts, which are manufactured components of automobiles. This list reflects both fossil-fueled cars (using internal combustion engines ) and electric vehicles ; the list is not exhaustive.
