Not a 12-cylinder engine, a triple-turbo 12-rotor engine. A 15.7-liter rotary engine. This is insane, and so is Rob Dahm.

Sikorsky on Monday detailed recent successful demonstrations with its “rotor blown wing” unmanned aircraft system (UAS), ...

That little single-rotor powerplant quickly evolved into the more typical two-rotor design one might see in a Mazda RX-7, for example. Then came a three-rotor, which first appeared in the Eunos ...

Sikorsky reported successful flight tests for its 115-pound, battery-powered twin prop-rotor unmanned aircraft.

The rotor blown wing (RBW) design directs the backwash from the propellers or rotors over the wing surfaces, reducing drag and increasing lift by increasing the velocity of the air.

We go through the best aftermarket performance brake rotors at different price points, and explain how they're different from regular brakes. Finding the right non-OEM replacement brake rotors for ...

The aircraft is meant to develop and mature rotor blown wing design, which can now be applied to larger aircraft for unmanned aerial logistics and even tactical ISR missions. Sikorsky announced it ...

Brake rotors are a crucial component of a vehicle’s braking system, cooperating with brake pads to slow down the car and bring it to a complete stop. High-quality brake rotors exhibit reliable ...

Lockheed Martin's Sikorsky has successfully flown its "rotor blown wing" uncrewed aerial system in both helicopter and fixed-wing flight modes, it announced Monday. The 115-pound twin-prop drone ...
