Napier Naiad
The Napier NNa.1 Naiad was a British turboprop gas-turbine engine designed and built by D. Napier & Son in the late 1940s. It was the company's first gas turbine engine. A twin version known as the Coupled Naiad was developed but both engine projects were cancelled before finding a market.[1] The Naiad was also used, in adapted form, in the Napier Nomad turbo-compound engine design.
