Rotorcraft come in all shapes and sizes, most commonly helicopters, but also gyrocopters, gyrodynes, and rotor kites, among others. All of these use the same concept of a spinning rotor ...

Being a central part of the motor core, rotor design is critical to motor performance and efficiency. Because electric motors can spin at up to 20,000 rpm and even more, the permanent magnets have ...

The brake rotors are an important part of the disc brake system found in most modern cars. Many vehicles have disc brakes on the front and drum brakes in the rear, while others have four-wheel ...

Meanwhile, drilled rotors have holes drilled into them, which both looks cool and promises better braking performance. Slotted brakes, on the other hand, are kind of like a more evolved version of ...

The Rotor Blown Wing is a hybrid-electric, fully autonomous flying wing aircraft. Credit: Sikorsky NASHVILLE—Sikorsky plans to fly a Group 3 design of its Rotor Blown Wing next month as the ...

The closest guess came from a reader named "Username" – who pointed out the larger diameter, more efficient rotors, but correctly said this wasn't enough by itself. Mazar tells me it's a ...

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 ...

However, the helicopter’s tail rotor was damaged during the emergency landing. This incident comes just days after a helicopter en route to Gangotri Dham crashed in the Gangnani area of ...

Abstract: This paper investigates the experimental implementation and detection of rotor faults in permanent magnet synchronous machines. Methods are shown how to experimentally introduce static and ...

Abstract: In the early stages of Rotor Interturn Short Circuit (RISC) for synchronous generators, the short circuit is often unstable and intermittent, leading to what is known a Dynamic Rotor ...
