Pyestock Diaries


home | documentation | literature

To date, only a small amount of documentation concerning the Pyestock site and the testing cells has surfaced. Whilst there's still vast amounts of test documentation around the site itself, this pertains to specific test results and doesn't offer an overview of the entire site.

Therefore the small amount of literature and documentation which is available is reproduced here.

Minstry Of Supply Document: © May 1954

Plant and Equipment for Aerodynamic and Combustion Testing

This Ministry Of Supply document was found in the Plant House and photographed in-situ. It appeared to be a specification of the building, the facilities it would provide and the plant it required. Whilst it appears the Plant House was built to these designs, the document also includes the original ideas for plant to be used in the building.

Both Pyestock and Whetstone are given on the cover, suggesting this document was written before the two sites merged at Pyestock.

The Aeronautical Activites Of The National Gas Turbine Establishment

This paper, given to the Manchester Branch of the R.Ae.S in December 1973, summarizes the organisation, function and physical testing undertaken at the site. It's an important document as it provides a snapshot of Pyestock before the new Anechoic Facility was built, and includes black and white pictures of the original Anechoic facility.

Recruitment Brochure

This colourful and extremely impressive Recruitment Brochure outlines the scope of the facility and includes many archival pictures of the staff, equipment, testing cells and buildings. It also features the Anechoic Facility; the only major part of the site still in use and firmly off-limits.

Engine And Component Test Facilities - Issue Three

This booklet was probably produced as introductory material for those starting work on the site, or for those wanting to use its facilities. It gives a thorough overview of the air supply installations, engine test facilities and the electrical, steam, water and fuel services; but also gives lengthy descriptions of the component testing facilities, research rigs and the noise absorber rig facility and anechoic chamber facility.

Engine Test Facilities - Issue Four

This booklet was probably produced as introductory material for those starting work on the site. Dated 1981, it gives a brief history of the N.G.T.E. before giving more detailed accounts of the Air Supply installations, the engine test facilities, data gathering techniques and the electrical, steam, water and fuel services.

Altitude Test Facilities

This six page brochure was packed with colour photographs of various test cells and their control rooms. It gives brief details of the altitude test cells and the capabilities of each.

DERA Brochure: © Circa 1995-2001

Pyestock Engine Test Facilities

DERA (the Defence Evaluation and Research Agency) was formed in April 1995 by the merging of the DGT&E and the DRA. This also consolidated the Pyestock site under one management unit again as parts were owned by each parent company. DERA continued to operate the site until July 2001 when most of the company was made public and floated on the stock exchange as QinetiQ.

Therefore this brochure was produced between 1995 and 2001. It outlines the engine testing taking place at Pyestock and the capabilities of each of the testing cells then in use. Interestingly it also refers to future plans for Cell 3 West, but it isnít known if these were ever carried out.

Pyestock: A Celebration Of The Gas Turbine Engine

Produced by DERA, this colourful and well-designed brochure covered the history of the development of the gas turbine and Pyestock. It also included many archive black-and-white photographs from the early days of the site.
