Armstrong Siddeley Viper

The Armstrong Siddeley Viper is a Turbojettriebwerk, which was developed and built by the British company Armstrong Siddeley. Since the company later became Bristol Siddeley in and Rolls- Royce, the engine was referred to as Bristol Siddeley Viper or Rolls Royce Viper.

History

The first test runs of the engine made ​​1951. 1953 was put it into service and is still in the Royal Air Force Hawker Siddeley in the HS.125 as training aircraft in service. It was originally to drive the Australian Jindivik developed as a simple, inexpensive " consumption engine " target drones, but later developed through the use of better materials to a standard engine. The original ASV.3 1640 lb thrust only had a projected lifespan of 10 hours. The later pattern ASV.5 and ASV.6 ( with as early as 1900 lb thrust), and the version ASV.8 1750 lb thrust were designed by the improvements and new materials for a far longer service life. Improvements that have been taken over by Sapphire, the ASV.11 with 2460 lb thrust and the weaker the benefit of a longer life ASV.10 with 2,000 lb thrust developed. Later, the Viper 20 and Viper 30 to come. In total, more than 5,500 engines of this type were built.
