Ansat-U helicopter

Six new multi-role Ansat-U helicopters have been delivered to the Sokol training air group of the Air Force Academy

Named after N.E. Zhukovsky and Y.A. Gagarin, RIA Novosti reports with reference to the official representative of Russian Air Forces, Colonel Igor Klimov.



“The helicopters departed from the airfield of Kazan Helicopters factory and headed to Syzran airfield. After refueling the vehicles headed from Syzran to Sokol airfield (Saratov Region). The duration of flight was about 3 hours,” Klimov said.

He said that at present Ansat-U is being operated by pilot-instructors. The academy’s fleet comprises 19 helicopters of the type.

“The academy’s cadets will start operating Ansat-U helicopters in 2014,” Klimov said.

Interesting tail design of the Ansat-U. I wonder if they get more yaw authority with less power out of it.

Perhaps. One thing is certain though, that without the additional vertical stabiliser the t/r is decidedly exposed. Usually the 'tailfin' offers some protection (on one side at least) for those wandering a little too close to the tailrotor.

I was wondering whether a laterally-mounted tail rotor guard (in the form of arced-shaped arms) would have been an idea but .. I can also see how under the wrong circumstances such a device could become a liability.

Either way, Ansat clearly feel that their horizontal-stabiliser-mounted vertical fins are 'enough' for the job.

I guess it's not as susceptible to weather cocking as other conventional designs when the wind is abeam.

Moreover all on Ansat U is FBW

Published during MAKS 2013 /& FLIGHT :
Russian Helicopters has finally achieved civil certification of the Kazan Ansat light twin, albeit with hydromechanical* controls rather than the fly-by-wire system initially proposed.

Kazan started work on the current iteration of the Ansat in 2011 after encountering difficulty in the certification process for the fly-by-wire controls. The first prototypes of the helicopter made their appearance in the late 1990s.

"No commercial fly-by-wire helicopter had obtained certification anywhere in the world, and there were no established requirements for such a helicopter," says Russian Helicopters.

To speed up the civil approval process, it dropped the more advanced technology in favour of a traditional control system.

Russia's defence military will eventually take delivery of the fly-by-wire-equipped Ansat-U trainer for its flight-training schools. Additional examples will be handed over to the Russian air force in November.

The civil Ansat is powered by a pair of Pratt & Whitney Canada PW207K turboshafts and boasts a maximum take-off weight of 3,600kg.
*hydromechanical controls are known one, from french origin...

Lynxski? Must have a fair bit of tail rotor roll in the hover.
