According to the company the latest helicopter is more efficient than ever, and the company has invested a lot for making the aircraft 85% more efficient and accurate.

It is the world’s first helicopter runs without a tail rotor. The company has named it Sherpa, and the Sherpa Helicopter has become the choice of every aircraft lover, as it has created with unique design.

The complete Sherpa Helicopter system is based only on a motor that powers the compressor. It doesn’t propel the rotor directly, but has its air intake at the rear side.The air is supplied from the compressor to maintain the engine’s combustion, while the cooling system remains in working condition during the process to provide necessary cooling. Two turbines propel each of the two engine rotors and they are in turn driven at the temperature of 100º C by compressed air.

Sagita claims that they have integrated a new system in the helicopter, and it has less moving parts in the engine during its flight. Therefore it has less need of maintenance of helicopter, as it is economic. Whereas the characteristics of the helicopter are concerned, they are detailed below.

  • The range of the helicopter is hypothetically calculated to be 400 km (250 miles) along with a cruise speed of 158 km/h, the predictable maximum flight time is 5 hours and it can attain an altitude of up to 2000 m.
  • It include 1.45 m (4.8 ft) wide and 1.26 m (4.1 ft) high cockpit, a bullet shaped fuselage for the air intake at the backside with the overall length being less than 4.8 m (15.8 ft).
  • Regarding the performance, Sagita affirmed that the 260 kg (573 lb) helicopter will be able to take off with additional 171 kg (377 lb) of payload. Sagita asserts to have verified the concept using a 1:5 scale model.

The above data is mostly theoretical, as the tests have been taken on a very small scale. The company has decided to take off the first flight in 2015, and after that its starting price will be  €150,000 (US$200,000). It seems that a lot of helicopter users will place preorders for the latest helicopter without tail.
