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 mechanical work through either linear or rotary motion. Linear motion can come from either a diaphragm or piston actuator, while rotary motion is ...
WJBF (channel 6) is a television station in Augusta, Georgia, United States, affiliated with ABC and owned by Nexstar Media Group.The station's third digital subchannel serves as an owned-and-operated station of The CW, in which Nexstar holds a majority stake.
The air compressed by the compressor bypasses the combustor and turbine section of the engine, where it is mixed with the turbine exhaust. The turbine exhaust can be designed to be fuel-rich (i.e., the combustor does not burn all the fuel) which, when mixed with the compressed air, creates a hot fuel-air mixture which is ready to burn again.
The gasifier turbine idled at 15,000 RPM and the power turbine operated at up to 28,000 RPM. Overall compression ratio in the gasifier stage was 3.5:1. [22] Turbine inlet temperature was increased to 1,650 °F (900 °C) from 1,500 °F (820 °C); after GM Research re-rated the temperature resistance of the GMR-235 superalloy.
A pneumatic motor or compressed-air engine uses the expansion of compressed air to drive the pistons of an engine, turn the axle, or to drive a turbine. The following methods can increase efficiency: A continuous expansion turbine at high efficiency; Multiple expansion stages; Use of waste heat, notably in a hybrid heat engine design
The compressed air is heated in the combustor and passes through the turbine, then expands in the nozzle to produce a high speed propelling jet [3] Turbojets have a low propulsive efficiency below about Mach 2 [ citation needed ] and produce a lot of jet noise, both a result of the very high velocity of the exhaust.

Eolo is the first compressed air-powered car. It was invented by Guy Nègre. Motor Development International (MDI) licensed the patent. It was unveiled during the 2001 Bologna Motor Show car and bike fair. An attempt to put it into production failed in 2003. The engine was sold as a power generator with zero emissions.
