The US Army is working to better understand the acoustic properties of eVTOL aircraft and co-axial rotors as part of efforts to design quieter, stealthier helicopters.
-
The 300-horsepower, supercharged 4-cylinder engine from the Kawasaki Ninja H2R has found a new home in an autonomous compound helicopter Kawasaki has been flight testing. And like the H2R, this K-Racer aircraft will be much faster than its peers.
-
After 34 years of service, during which it clocked up 933,614 flight hours, the United States Marine Corps is retiring its fleet of 179 Bell AH-1W “Super Cobra” attack helicopters, though some have been converted to their successor, the AH-1Z Viper.
-
Airbus Helicopters' VSR700 unmanned aerial system (UAS) prototype has flown autonomously for the first time. At a drone test center near Aix-en-Provence in the south of France, the pilotless rotorcraft performed a 10-minute free flight.
-
The US Army has awarded BAE Systems US$179 million to produce the next-generation Missile Warning System to protect the Army's rotorcraft.
-
Airbus Helicopters' multi-role H160 helicopter has received type certification from the European Union Aviation Safety Agency (EASA) and it is now expected to gain US FAA certification before commercial deliveries begin later this year.
-
Helicopters regularly have to get their rotor blades inspected, so they can be replaced if they're wearing out. Using the BladeSense system, however, the aircraft would be able to monitor the condition of their blades in real time, while in flight.
-
While it's important to get fresh seafood from fishing boats to restaurants ASAP, using a full-size crewed aircraft to do so isn't always cost-effective. That's why Yamaha and Japan Airlines are now looking at using a drone for part of the journey.
-
The US Army has reduced its Future Attack and Reconnaissance (FARA) competition to two contenders. Bell's 360 Invictus and Sikorsky's Raider X have been okayed to proceed to the prototype phase of a new "knife fighter" small assault helicopter.
-
One of the good things about drones is the fact that they can safely be flown in conditions that would prove hazardous for crewed aircraft. That's where the JC260 unmanned helicopter comes in, as it's designed to fight forest fires.
-
Ordinarily on a helicopter, the main rotor is mechanically linked to the tail rotor, so the spinning of the former causes the latter to do likewise. A new system replaces the tail rotor with four fans, potentially making for safer and quieter flight.
-
Airbus Helicopters' VSR700 unmanned naval helicopter prototype recently successfully completed its maiden flight. On November 8, 2019, at a drone test center in the south of France, the aircraft carried out a series of tethered flights.
