Helicopters can be as dangerous as they are valuable, in part because of a phenomenon called rotor wash. What is rotor wash, ...

By now, you're probably aware of just how versatile and equally adaptable helicopters are. These aircraft are among the best ...

RC helicopters have quite a few differences than passenger and military helicopters, which is why they can fly upside down.

Helicopters also use those same rotor blades for thrust. While flying, the pilot tilts the rotor disc in the direction they need to travel. Tilting the blades allows a pilot to move a helicopter ...

Technically, any gas-powered turbine that makes thrust by expelling hot gases at high speeds qualifies as a jet engine. However, turbojet and turbofan engines generate forward motion. Helicopters ...

In fact, helicopters were preceded by autogyros, which used unpowered rotors that, like windmills, spin and generate lift when the autogyro is moving forward due to the thrust of a propeller.

Helicopter Engine Condition Trend Monitoring allows operators to review engine trend data to recognize significant trend ...

In the S-97, with the Advancing Blade Concept, the helicopter can reduce rotor pitch while flying at high speed and rely primarily on the pusher prop for thrust. Dive on Target ...

failure. With the new design, he found he could marginally control the helicopter in a hover and in forward flight at speeds up to 64 kph (40 mph). However, Henry discovered that the helicopter did ...

Airbus Helicopters continues to eye novel architectures for future rotorcraft designs, ... This would be shaped to generate sideward thrust and also contain a propeller for use in forward flight.
