AVIC developing ultrafast tilt-rotor aircraft

Chinese helicopter designers are focusing on the developmen­t of an ultrafast tiltrotor aircraft capable of flying 500 kilometers per hour, the nation’s top helicopter researcher said.

Wu Ximing, chief helicopter designer at State-owned aircraft giant Aviation Industry Corp of China, told China Daily on Monday that researcher­s at the company’s Helicopter Research and Developmen­t Institute are developing the Blue Whale tilt-rotor aircraft, China’s equivalent of the United States’ Bell Boeing V-22 Osprey.

“We will design two variants of the Blue Whale — a medium-duty typeanda heavy-duty one. The medium-duty model will have a maximum takeoff weight of 20 metric tons, and the heavy-duty model 40 tons. Wu Ximing, chief helicopter designer at Aviation Industry Corp of China They can fly as fast as 500 km/ h,” Wu said.

Modern helicopter­s usually have a maximum speed ranging from 250 to 300 km/h.

The aircraft will be able to conduct vertical takeoff and landing in tough terrain like a convention­al helicopter, and will have a longer range and higher cruising speed that can compare to turboprop jets, Wu said, adding it can also carry heavier payloads than helicopter­s.

With four rotors, the Blue Whale will have better reliabilit­y, maneuverab­ility and safety than its US counterpar­t, the V-22 Osprey, he added.

Wu expects the tilt-rotor to conduct a wide variety of tasks, such as disaster relief, supply airdrop and other emergency response operations.

AVIC sees the importance of developing the ultrafast tilt-rotor aircraft, he said, adding, however, that it will be a long time before they are ready for mass production due to technologi­cal complexity.

An earlier report by China Aviation News, a newspaper owned by AVIC, quoted engineers at the Helicopter Research and Developmen­t Institute as saying that the Blue Whale will have a flight range of 3,100 km and meet demands of rapid troop deployment of the Chinese army and navy.

The US is flight testing the Sikorsky S-97 Raider highspeed armed helicopter. Sikorsky Aircraft, the manufactur­er, said it has a cruising speed of 407 km/h, morethan 100km/h faster than the US’ Boeing AH-64 Apache that is widely considered the best combat helicopter in the world.

Russia is also researchin­g designs for a stealth combat helicopter with ultrafast speed, Russian media has reported. the
