Glimpses Of The Future

Russia Flies Prototype VTOL Aircraft

Russia’s Foundation for Advanced Research has already flown a 60-kg (132-lb) prototype of its Cyclocar VTOL aircraft, which uses a super-responsive cyclical propeller propulsion system. A full-size, long-range, six-seat Cyclocar is expected to fly in 2022.

We’ve seen this cyclic propulsion system before, from Austria’s Cyclotech, which was previously known as D-Dalus. It places a number of variable-pitch blades in fast-rotating barrels. Each blade changes pitch constantly as the barrel spins, meaning each corner of the aircraft can vector its thrust through 360 degrees nearly instantly, without changing the RPM of the motors.

While this would make cyclic propulsion a terrific solution for a gasoline-powered VTOL, the Russians are planning to use it with a hybrid propulsion system, with full electric drive and a range-extending combustion generator.

The six-seat aircraft is expected to fly at up to 250 km/h (155 mph) – this is a fair bit slower than many lift and cruise or vectored thrust multicopter designs, presumably because it has no wings and needs to keep its thrust vectored partially downward at all times.
