Hi Peter Part of the answer is that Mazda found it difficult to comply with the strict emission standards set for the car industry. Fortunately the same standards do not apply to the aviation industry and for this reason both the two stroke engines and the Austro rotary engine are today in widespread use for relatively low powered gliders.
Perhaps I should use this opportunity to correct a few rumours around the Austro rotary engine used in all eleven ASK 21 Mi for the Australian Air Force Cadets. It is true that one of these engines exceeded the flight manual temperature limits by two and another engine by four degrees during ferry flights on a hot day. However, claims that the engines overheat are simply incorrect! Correct is that Schleicher adopted the engine manufacturer's temperature limits in the ASK 21 Mi flight manual but elected to use a different temperature sensor location for ease of accessibility. This minor change has resulted in temperature readings about 10 to 15 degree higher compared to figures established during the certification process of this rotary engine Right now Austro Engines and Schleicher are issuing revised flight manual pages which brings the matter to an end. It is also important to highlight that issues beyond the control of Schleicher made the Air Force decide not to utilise the self launching capabilities of the ASK 21 Mi at present. Please stay tuned to this channel for an update in the not too distant future!
