Specification
The GRAUPNER G-BOOSTER series of model turbines works in a similar fashion to
full-size jet aircraft power plants. Air is sucked into the engine and
compressed by a single-stage radial compressor. The air is then mixed with fuel
in the combustion chamber and heated by a fuel flame. As the mixture burns, the
air mass expands massively and is forced out of the engine, passing through an
axial turbine wheel, which in turn drives the compressor via a shaft (cycle
effect).

Heward Microjets Heward Microjets Limited was founded by Phillip G. Heward the well known gas turbine designer since 1983. (He formerly founded Microjet Engineering Limited in 1995, and personally designed/ manufactured all engines sold by them). We are proud to present our exciting new range of gas turbine engines.
From the designer of such classics as the Phoenix MK4, the Panther HF15, the HF65/100/150...etc come four recently developed, brand new engines: the, Wasp 2 H20, the Cirrus H65, Nimbus H80 as well as the Altair H400 Turbofan.
Please keep an eye on the News and Current affairs page as this is being updated on a regular basis with details for all engines. as is the FAQ page, please do continue to email us with more of your requests and queries so we can build up a more helpful range of information.
Our Engines The engines designed by us have many applications, both conventional and unorthodox: for land based-vehicles; aircraft ranging from models to UAVs and manned ultra lights and gliders; turbo shaft units for power generation, helicopters and turboprops. We are currently working on a series of small Turbofan engines in the thrust range of 150 - 400 lbf. As well as our standard range of engines, we can also build custom units for specific applications.

About Wren
Wren Turbines was formed in 1999 by Mike Murphy, John Wright, Roger
Parish and Terry Lee. They had a shared interest in miniature
turbines and had met through the Gas Turbine Builders Association.The name was chosen because the Wren is commonly regarded as the smallest British bird and the company intended to specialise in the smallest engines. The first Wren engine was the MW 54, designed by Mike with help from John. The designation comes from their initials (Murphy Wright) and the size of the compressor in millimetres. This was the first miniature engine to use a compressor size of less than 66mm, making it much smaller and lighter than all the previous engines. It was available first as a set of plans and castings for homebuilders and then in January 2001 the MW 54 kit (Mk 1) was launched. This was followed by the Mk 2 (5.4 kg thrust) in January 2002, and the Mk 3 (6.4 kg thrust) in June 2004. The kits are very popular and are frequently bought by first-time jet fliers. The kit is fully balanced, easy to assemble, and there are over a thousand of the engines being flown all over the world. The MW54 is also available as a ready-built engine. This was followed in 2002 by the Wren Turboprop, the first miniature two-stage engine. Like the MW 54 which is used as the first stage of this engine, it was available first as a homebuild plan, with detailed instructions for making the gearbox and a set of machined castings for the second stage. The following year the engine became available as a ready-built engine. It has undergone considerable development since and is now flown by some of the world’s top show fliers, including Thomas Gleisner (Airworld Raven) Quique Sommenzini (YAK 54) and Ali Maschinchy (Spitfire). The development of the two-stage engine made it possible for people to build helicopters with Wren Helicopter engines. At first, gearboxes and conversion kits for helicopters were only available through third parties, and a number of customers designed and built their own gearboxes. The Wren helicopter gearbox completed the engine in Autumn 2004 and made it possible for customers to buy everything needed for a turbine helicopter, directly from Wren. The MW44, the smallest Wren engine, appeared in April 2003. This was another “first” for Wren, an engine with a 44mm compressor, about the size of a coke can, yet with 3kg of thrust. At first it was only available with a hand starter and then later with onboard start. There was much interest in an Autostart version but it proved very difficult to get this tiny engine to autostart reliably. In the summer of 2005 the MW44 was temporarily withdrawn from the market and more development work was done, resulting in the new MW44 Gold, an engine with Autostart, faster response and over 4kg thrust. Wren’s most recent engine is the SuperSport, launched in March 2005. This is a development of the MW54 and is the same size but produces 8kg of thrust. It uses a new cast diffuser system and other innovations from the Wren team, giving it an exceptional power-to-weight ratio. Wren is a company dedicated to the design and manufacture of miniature jet engines – we don’t do anything else. We employ 8 people in our factory at Manvers, Rotherham, UK. All the design and tooling for the turbine castings is done in-house and the turbine wheels are cast in specialist foundries to full aerospace certification. We are proud of the quality of our engines and the service and support we give to our customers.

How a model jet turbine works
A model jet engine design can vary from one manufacturer to another, but
they all work on the same principle. The most common type nowadays is the
centrifugal flow turbine, as opposed to the lengthier axial flow
turbine. The fuel, which is nearly always kerosene ('Jet A1'), is introduced into
the combustion chamber as a very fine spray, and so mixes easily with the
now very compressed air. This fuel/air mixture is then ignited by a small
glow plug, much the same as the one found on a 2 or 4 cycle model airplane
engine. As the fuel/air mixture ignites and explodes within the chamber, it is
forced rearwards towards the turbines. The turbines accelerate the velocity
of the passing gases, and increase the pressure of them too. The gases
(exhaust) finally get squeezed through the narrowing jet pipe at the very
rear of the engine, exiting at great speed and pressure, thus generating the
high levels of thrust. The drawing below shows the basic principle of a centrifugal flow model
jet engine.
Most model jet engines use an electric motor to initially power-up the turbine. Only when the compressor has reached the necessary revolutions per minute (RPM), can the fuel be introduced into the chamber and the engine can then operate normally.

Afterburner Effect A very realistic afterburner from Flugmodellbau.biz a very powerful effect: The afterburner ring, designed to work with Multi light mini or Multi light Pro 3 gives you the optical effect of an afterburner at your jet model. A basic current is applied plus an additional intermitting current showing the effect of a burning flame. Very impressive from some hundred yards of distance. The ring may be switched from the RC via separate switch or you may use it parallel to your gas-channel (V-cable). The switching point could be programmed at the electronic board.
