The Aircraft Engine Historical Society is a non-profit educational and historical society that fosters an appreciation of the people, art, and science associated with aircraft engine development, manufacture, and use.

Aircraft Engine Starter

Accessories

Accessories complete the engine. Carburetors, fuel injection systems, starters, magnetos, generators, hydraulic pumps, and turbosuperchargers are all accessories. While these are usually supplied by specialty manufacturers, they are nonetheless essential to the operation and performance of the engine. And like engines, they have development and operation tales of their own.

Airbus A380 Blade-Off Test (Long Version)

An explosive charge servers one fan blade thereby destroying the engine. This is to determine whether rotating parts are contained within the engine.

Torque Meter

Journal of the Aircraft Engine Historical Society

For seven years the AEHS published a prestigious quarterly journal, Torque Meter, which contained articles on all types of aircraft engines, both new and old. Topics included engines and the aircraft they powered with emphasis on the engine installation, propellers, accessories, cooling, operation, and maintenance.

Torque Meter is no longer published. However,

All Torque Meter Back Issues Are Still Available!

Help Needed:
Bristol Centaurus

An Australian group is overhauling a Type 18 Bristol Centaurus engine. The intention is to return this engine back to Airworthiness, and then be reinstalled back into the Sea Fury that is also being overhauled to Airworthy standard.

Whilst we do have some parts and information for this job, we would like to know more! If anyone has information, or knows of someone that may be familiar with the machining process involved in the manufacture of the sleeves, and even the machines used for this job, it would be greatly received and very much appreciated.

We do have some information (metallurgy content , tolerances) but we would like some of the finer details of the machining process, and the machines they were produced on. If anyone has this information, please pass it on via

Thank you.

Rolls-Royce Merlin Book

The Rolls-Royce Heritage Trust is putting together a book about the Merlin engine. We would like to include a list of surviving engines, and to this end any help would be appreciated.

All that is required is the mark and serial number of the engine, be it airworthy, on display, in a museum aircraft or in private ownership. Engines must be complete or substantially complete - no wrecks. All marks are eligible for engines made in the UK, USA and Australia.

We hope to collect serial numbers of all Packard Merlins, including the -3, -7 and -9s, etc., in Mustangs/museums/privately owned (even those built by Continental). Any such knowledge about Merlins other than those in USA/Canada would also be helpful.

If anyone would like to provide me with such details they can e-mail me through
