As a petrol head I yearn for more power and speed in anything I own and my aircraft are no different. I have successfully turbocharged my bush wacker, my 7-year-old daughter’s quad bike and I am looking in to turbo-charging my ride-on lawnmower to cut down on maintenance time in the garden. I have been looking at a performance upgrade on my Bat Hawk for while now and have come up with a solution that was just sheer genius.
This all started one day when I was passed at low level by a Pilatus PC-12 while on a scenic flight around the Lowveld. That day I told myself I will never be overtaken by one of these ever again. As a man that does not look for a solution to a problem that should never have existed in the first place I did very fine planning and my concept is genius to say the least!
Running a Rotax motor I first thought of Supercharging the engine. The problem is that I would need so much engine power from the Rotax engine to drive the Supercharger that this idea was not on the cards. I carefully proceeded to my next innovative and well planned step. To achieve the projected speed of around 300 knots and a service ceiling of 20 000 feet I needed a very large turbocharger to be fitted to the engine.
The other problem was that the small Rotax motor would only be able to “ spool “ up the large turbo at very high revs and as a result I would lose cruise speed and instant rate of climb.
So I fitted another Rotax engine facing the rear and fitted with this engine, a smaller turbocharger. The whole concept of forced induction was adapted by myself to get to my ultimate goal of successfully turbocharging the first engine at the front.

Taking Flight On Another World
The Mars Helicopter, Ingenuity, is a technology demonstration model to test powered, controlled flight on another world for the first time. It hitched a ride to Mars on the Perseverance rover. Once the rover reached a suitable "airfield" location, it released Ingenuity to the surface so it could perform a series of test flights over a 30-Martian-day experimental window.
