Williams WR44
Williams WR44 was a two-shaft turbofan.
In February 1978 Foxjet International signed an agreement with Williams Research Corp. (WRC) for exclusive supply over three years of the 800 lb WR44-800 to power the new Foxjet light executive jet.
Under the agreement Foxjet would pay for certification and other costs of the engine programme.
The new turbofan replaced the original WR19-3-1, giving WRC its first entry into the general-aviation market.
A derivative of the WR19, the WR44 has had its bypass ratio reduced from 5:1 to 3:1, and its pressure ratio increased.
