Objetivo This project addresses a new concept in light aircraft power plants. In 1993 JMA Propulsion Ltd. won one of the UK Department of Trade and Industry's SMART Awards for its compression ignition aero-engine of low weight and high specific power output of a modular design. The configuration was that of a turbo charged compact diesel engine which reduces atmospheric pollution, noise, fuel consumption and fire risk, increases range, provides a high power: weight ratio and significantly reduces torsional vibrations. During the two years following this award, the company has used its experience gained to design a range of modularised two stroke diesel aero engines and it on this that the current proposal is based. While the main components are generally ot a tried and tested design, the configuration is entirely new and is justified by the significant direct benefits of reduced total product and operating costs, reduced fire risk to personnel and reduced environmental intrusion by noise. The level of torsional vibrations associated with conventional diesels has prevented them being harnessed easily to an aeroplane propeller due to uneven twisting action of the crankshaft and consequent risk of propeller failure. The configuration of the JMA Ashton engine concept results in a considerable weight saving due to the engines inherent balance and the reduction of unbalanced loads reaching the crankshaft. The JMA Ashton engine is well suited to running on renewable fuels, such as vegetable oils, due to the very high cylinder swirl engineered into the design which increases thermal efficiency and reduces emissions. Engine emissions are reduced by ensuring that there is always a surplus of oxygen compared to amount of fuel being injected. The first mechanical demonstrator engine will have a blower and supercharger. Eventually this will be achieved by using a new design of super charger that is engine driven at low engine revolutions and thus acts as an extremely efficient supercharger until sufficient exhaust gases and temperatures are achieved (normally around 1500RPM). Additionally the use of this novel turbo charger unit instead of the usual super charger blower and conventional turbo charger combination allows the engine weight saving of around 6% and increases the engine output by an estimated 8%. The JAR type validation of the modularised engines will need to be undertaken by the industrial SMEs in a six months period prior to subsequent commercial exploitation. It will involve the performance testing over a wide application range and the production development after completion of this two year research project.
