Designing an engine is the hardest part. Fitting the engine to an airframe is not as hard and requires pure engineering. That’s what we do as well in a very close communication with the target customer or airframe designer. Engine mount, cooling the water, cooling the air and keep it all acessible for the maintenance crew plus allowing air to enter the cowling as well as making sure that the hot air can leave the cowling – that’s the part where experience meets design capabilities.
