Noel Penny Turbines was a British company that produced small[1] jet engines, most notably the Noel Penny NPT301.[2] It was established in Coventry in 1972 by Noel Penny, a former designer and chief engineer from Rover Gas Turbines in Solihull. The company employed hundreds of engineers at its works at Siskin Drive, Tollbar End in Coventry over a period of two decades. It eventually went into receivership in 1991, with the rights to the engine designs being sold off.[3] [4]
In the 1970s, Noel Penny Turbines undertook secretive contract work for the American company, Caterpillar Inc. in the design of engines for heavy vehicles and trucks.[5]
