The PFM Flugfest 2016

Meeting of PFM planes, Porsche cars, bicycles and tractors.

Saturday 6 August 2016, Heubach Germany, home of PFM planes:


.......International Meeting for Robin, Cessna and Mooney PFM powered aircraft.


Am 6. August ist es wieder soweit. Dann treffen sich auf dem Flugplatz in Heubach wieder die letzten verbliebenen Flugzeuge mit Porsche-Flugmotoren. Porsche-Flugmotoren-Experte und Initiator des Trefffens, Uwe Sauter, rechnet bei gutem Wetter mit rund zehn Maschinen. Da bereits drei Porsche-Clubs ihr Kommen zugesagt haben, gibt es  darüber hinaus aber auch jede Menge Porsche-Automobile zu bestaunen. Ein besonderes Schmankerl planen wir mit der Elster. Ursprünglich mit dem Flugmotor 678, einem Ableger des Porsche 356 ausgerüstet, wollen wir sie zusammen mit einigen besonders schönen Porsche 356 präsentieren. Vom Speedster übers Cabriolet bis zum Coupé. Zudem unterstützt uns das Porsche Zentrum Schwäbisch Gmünd mit einigen erlesenen Porsche-Modellen aus dem aktuellen Programm. Das Kommen lohnt sich also in jedem Fall, zumal auch wieder Mitfluggelegenheiten angeboten werden.

Sovereignty in the sky

In August, at the invitation of Porsche aircraft engine specialist Uwe Sauter, Heubach Airport near Stuttgart was again transformed into a Mecca for exclusive aircraft that have a history with Porsche.


The sportscar manufacturer’s aircraft engines make up a small but extremely interesting chapter in the rich history of Porsche. It is a story which reaches far back in time, as more than 100 years ago Ferdinand Porsche also used aircraft engines to establish the reputation of a diverse engineering company that would later become the company Porsche.

In 1955, when the aircraft engine ban in Germany was lifted in line with the Paris Agreements, it was recognised at Porsche that the air-cooled four-cylinder boxer engine of the 356 would also be suitable as the basis for an aircraft engine. And so came about the Porsche 678 aircraft engine with power outputs from 52 to 75 hp, which was built right into the 1960s, and powered among other things the prototype of the first German post-war aircraft to be built in significant numbers, the Pützer Elster. Since September 2010, the Porsche Museum has therefore looked after the company’s tradition not only on land but also in the air, with a carefully restored Pützer Elster B (, even if the series production machine does not have a Porsche engine due to maintenance and spare part requirements.

Flight testing for the Porsche aircraft engine

Later, Porsche took up the matter of aircraft engines again. Similarly to the development of the Type 678 aircraft engine, in the early 1980s it was the six-cylinder boxer from the 911 that caught people’s attention, and in September 1983 flight testing began for the Porsche aircraft engine PFM 3200, with a displacement of 3200 cubic centimetres. To comply with the redundancies required for aircraft engines, the 204 to 220 hp engine gained a dual ignition and two alternators, and the camshaft drivetrain was converted from chain to spur gears. It became known in the history of aviation as the “whispering engine”, and indeed it runs very quietly even for today’s standards and is impressive in its excellent consumption values. Thanks to fuel injection and optimum-efficiency reduction gear, a Mooney for example consumes just 35 litres per hour instead of the 50 litres or more typical for a Lycoming engine.



Uwe Sauter takes care of the maintenance of Porsche aircraft engines

In times like these when fuel is precious and above all expensive, this is just one good reason to tend to and look after the Porsche engine, and Uwe Sauter from the airport in Heubach is today’s global specialist in this. In the early 1980s, he became involved in the development of this power unit in Weissach, and since leaving the sportscar manufacturer after the production and development of the PFM engine was discontinued in 1991, he has taken care of the remaining 22 of around 80 engines originally built in Europe, Australia and the USA.

Every few years, Sauter invites the pilots of the Porsche faithful to come along with their planes and this time, thanks to wonderful summer weather, no less than nine treasures of aviation still equipped with the PFM 3200 engine lined up next to the Pützer Elster and the Scheibe Sperling. Among them, the two former Weissach experimental aircraft for engine testing of the Cessna 182, the Weissach Mooney made to test the PFM 3200 Turbo which never entered series production, itself on the verge of being completely restored, and the famous flight-around-the-world Mooney, with which Porsche proved the reliability of the new aircraft engine in a circumnavigation of the globe in 1985.
