Possibilities to reduce propeller aircraft noise, including diminishing the propeller diameter, profiling the propellers, and using new propeller construction material such as wood-composite material, are discussed. Future developments are outlined: engine performance and thrust, new types of engines, and lowering of propeller speed.
