Wren 44 Demo Rig

One of two test stands custom made by Wren for the RAF to demonstrate jet engine technology in schools/colleges in a recruitment drive

Wren 44 Shaft Power Engines


Wren Power Systems’ jet engine products were mainly aimed at the leisure flyer market but Wren recognised there was a clear need for high quality miniature gas turbine engines that were specially prepared for use as educational tools, for students of thermodynamics and engineering.

Wren’s new LAB  engine includes a cabinet trolley and enclosure to mount all the items including the engine,  a metal fuel tank, a mass flow intake sensor and a protective cover to protect the engine section. The unit features seven standard pressure and temperature ports, the base amplifier section with 19 analogue outputs and 15 switched outputs for external monitoring via industry standard 37 pin connector and integral power supply.   The hand control can be used mounted on the trolley or by remote.

Wren also offers engines, for demonstration use, such as the 100N miniature gas turbine engine, twin engine unit and cutaway gas turbine engine. For those who want to assemble an engine we  supply a gas turbine engine kit, complete with all the parts, mounting and instructions to build the complete engine.


We have prepared engines by special request to an educational equipment company using our very small 44 size engine (4.5kg). These were prepared to full LAB specification with a full range of ports and sensors in a very small package. These were shaft power engines for connecting to generators and/or dyno-rigs. We can also offer a similar package arranged as a turbo-prop for propeller drive with thrust and torque sensing. These are really small engines which run very quietly and being so very compact can be considered as practical for desktop installations due to their very small size.
