Gas turbines are increasingly used as power plants for a wide variety of applications around the world. Originally they were developed solely for aircraft propulsion where their inherent low specific weight (i.e. mass/unit power) made them essential for high speed flight. For this particular purpose they have been developed to a high degree of efficiency both thermodynamically and mechanically. Industrial gas turbines have been and are being developed for such diverse applications as electrical power peak lopping stations, firefighting pump sets, natural gas pumping and compressor units, factory power and process heating plants, heavy lorry propulsion, rail and ship propulsion. Cussons has designed and manufactured educational gas turbines since 1970 and numerous universities use our gas turbines for experimental and practical demonstrations.
