News, facts, and comments on the coming revolution for piston-engine aircraft.
In 1998, one diesel engine flew on a converted airplane for the first time since 1945. Today, close to 4,000 singles and twins are flying. This is the beginning of a worldwide trend which will eventually allow a rebirth of the piston-engined aircraft, around new specs and new missions.

Introducing the Raikhlin RED A03 500HP aero diesel.
Press Release: Raikhlin Aircraft Engine Developments GmbH, a new venture founded by Wladimir Railkhlin and his associates, successfully completed a full-scale flight test of the most powerful modern diesel piston engine designed for General Aviation. Initial flight test on a modified Yak 52 is the beginning of the exploration of defined parameters for RED A03 engine installation within which the engine may operate – from normal to extreme conditions. It is a water & oil-cooled double OHC, V12, common-rail direct injection engine. The propeller is gear-driven (single-stage, 1/1.67 ratio). Compression is 16.5. It is the product of RED Aircraft GmbH in Adenau, Germany. Testing location was limited by the range of the telemetry equipment on the ground. The engine generates 370 kW (500HP) take off power in basic specification, at around 3,900 rpm, showing a specific (JETA/diesel) fuel consumption of 210-220 gr/kWh. Full spec. engine weight at the moment is 320 kg (705 Lbs.),- two alternators, starter, engine/gearbox oil heat exchanger, prop governor. Initial test data showed the engine performance met all expectations, says RED’s management. Information collected from this test, together with data from former development tests, will be evaluated to better understand the performance and reliability of the design. Indeed, the RED A03 bridges the traditional gap between piston engines and substantially more expensive turboprops. RED Aircraft GmbH is in DOA and TC certification process with EASA.
Comments: 210-220 g/kWh means it is a very good diesel engine, comparable to the best. It is not a breakthrough. The weight seems indeed attractive, however one should assess the weight per HP only once the engine is retrofitted on the plane, and the plane demonstrates total reliability of engine in all conditions, any lapse in reliability meaning a modification which invariably brings the weight up. If properly designed, there can be nothing wrong with it, except the usual concerns about the geared propeller. But it comes filling a gap at a time when pro-diesel arguments (fuel economy, constant specific consumption, lower price per HP as turboprop) will certainly move to 600HP to frontier between piston engine and turboprop.

Every month: news, facts, and comments on the coming revolution for piston-engines aircrafts between 130 and 400 HP: Retrofitting a diesel engine to run on Jetfuel or Kerosene, reduce Gallons/Hour by some 30%, eliminate ignition systems (magnetos, spark plugs) and their problems, eliminate mixture control, increase TBO to 2,400-3,000 hours, increase performance between 6,000 and 12,500 ft., and drastically reduce Operating Costs.
The letter is intended for piston engines aircraft owners, manufacturers, fleet operators and FBOs, re-manufacturers of engines for these aircrafts, manufacturers of engine components and ancillaries, and all professionals acting in decisions of engine exchange or refitting at TBO, in North and South America, Pacific Rim, African continent, and all parts of the world were Avgas, Mogas, Kerosene and Jetfuel are available.
