THE primary purpose of this paper is to discuss some of the most pressing problems involved in choosing the propeller that is most suitable for use on a particular airplane. Propeller design is not ...

When you're at an airport and see propeller aircraft, you likely think it is powered by a piston engine. This is usually true among smaller planes, like the Cessa 172 Skyhawk and the Piper Archer, or ...

Hartzell’s 5-blade composite propeller reduces aircraft weight by around 20 pounds total by using carbon fiber construction ...

Certain propeller driven aeroplanes are equipped with piston engines whose fundamental "firing"-frequency coincides with the rotational frequency of the propeller. Taking the two sources as a system ...

Question: Why are the hurricane hunter planes only twin turboprops and not the regular fan jets that passenger planes use? Answer: The turboprops are more tolerant of hail than the jets. Airplanes ...

Diesel engines are a rarity in aviation history, but they've carved out an interesting niche. While most aircraft rely on gasoline-powered piston engines or jet turbines, diesel has offered some ...
