All vane type air starters should have a lubricator installed to insure long-life and maximum performance. [4] Lubricators give the moving parts a needed friction barrier, reduce metal corrosion and keep vanes sealed properly against the cylinder walls. Even the so-called lube-free air starters require lubrication to prolong trouble free life.
An interesting feature of all three German jet engine designs that saw production of any kind before May 1945 (the German BMW 003, Junkers Jumo 004 and Heinkel HeS 011 axial-flow turbojet engine designs) was the starter system, which consisted of a Riedel 10 hp (7.5 kW) flat twin two-stroke air-cooled engine hidden in the intake, and ...
The first mechanically powered submarine, the 1863 French submarine Plongeur, used a compressed-air engine. Musée de la Marine (Rochefort). A pneumatic motor (air motor), or compressed-air engine, is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed-air energy to ...
The engine was first tested on the Pratt & Whitney Boeing 747SP on July 11, 2008 through mid-August 2008, totaling 12 flights and 43.5 flight hours. [14] It then flew starting October 14, 2008 on an Airbus A340-600 in Toulouse on the number two pylon. [15] Testing of the CSeries bound PW1524G model began in October 2010. [16]
This bleed air is directed into a mechanism to start the engine turning and begin pulling in air. The starter is usually an air turbine type, similar to the cartridge starter, but uses the APU's bleed air instead of the burning gases of the propellant cartridge. Most cart starters can also use APU air to turn them. When the rotating speed of ...

AE 3007 on an Embraer ERJ 145. In 1988, Allison Engine Company (then owned by General Motors) and Rolls-Royce plc began joint studies of a 33 kN (7,400 lb f) RB580 to power the proposed Short Brothers FJX regional jet, combining the T406 core with a Rolls-Royce low-pressure spool.
A critical element in vane motor design is how the vane tips are machined at the contact point between vane tip and motor housing. Several types of "lip" designs are used, and the main objective is to provide a tight seal between the inside of the motor housing and the vane, and at the same time to minimize wear and metal-to-metal contact.
