Armstrong Siddeley Python

From Wikipedia, the free encyclopedia

The Armstrong-Siddeley Python was an early British turboprop engine designed and built by the Armstrong Siddeley company.

Its main use was in the Westland Wyvern carrier-based heavy fighter, the turboprop engine replacing the Wyvern prototype's original Rolls-Royce Eagle 22 piston engine. In this application, the Python was rated at 4,110 EHP.

Early flight-testing of the Python was carried out using the Lancaster B.1 (FE) TW911 and the Lincoln B.2 RE339/G, each aircraft having the two outboard Rolls-Royce Merlins replaced by Pythons. Lincoln B.2 RF403 also had two Pythons similarly installed and was used for high-altitude bombing trials at Woomera, South Australia, the Pythons being used to increase the height from which tests could be carried out.
