Why did Germany use inverted engines for most of their air craft during the Second World War?
Did other countries ever adopt the use of inverted engines in their aircraft?
Yes, a number of other countries have used inverted engines in their aircraft. For example, the British designed the Rolls-Royce Merlin engine, which became one of the most widely used inverted engines in the world. The United States also used inverted engines in a number of their aircraft, including the P-38 Lightning and the P-39 Airacobra.
