Constant speed propellers were designed to keep engine RPM stable, often around 2,700 RPM, even as flight conditions changed. Instead of the pilot constantly adjusting power, the system automatically ...

Most ships control speed by changing engine power, but vessels with controllable pitch propellers adjust the blade angle instead. This video explains how variable pitch systems generate forward or ...

It is more fuel-efficient to maintain a steady speed because the total energy used depends on the average air resistance. Since air resistance is proportional to the square of speed, your average ...

It's fairly common knowledge that when a supersonic aircraft approaches the sound barrier, what follows is the sonic boom. This transitory period between subsonic and supersonic, known as transonic ...

When one thinks of the average airplane, odds are that propellers are part of that mental image. They've been a crucial component of airplane construction from the moment air travel found its footing ...

With the growing popularity of electric propulsion, Gori recognized a demand for regenerative power. Traditional Gori propellers fold automatically when the engine is off to reduce drag, but they were ...

For 50 years, Danish company Gori Propeller has been one of the foremost names in folding marine propellers used on sailboat auxiliary motor drives. These propellers fold into a streamlined form when ...
