The Challis Heliplane: 300 Mph Tilt Rotor

November 17th, 2008 by BallerRide View Comments

Designed to hit speeds up to 300 mph, the Challis Heliplane is a concept aircraft that aims to be the world’s fastest rotorcraft.  When produced, the Challis Heliplane will be capable of twice the cruising speed and almost twice the range of a conventional helicopter.

Like other heliplane designs, the Challis will be able to fly in a continuous stable hover and reach high cruising speeds.  The simple design will reduce production and maintenance costs, making the Challis a relatively affordable way to book it through the skies.

Right now Challis has a completed design for a UAV (unmanned aerial vehicle) capable of hitting 280 mph and carrying a useful load of 250 lbs.  Challis Heliplane, the company behind the concept, anticipates building models to accommodate the full spectrum of weight categories and uses, from military to civilian.

Until a full-sized model emerges from the Challis production facilities, their 12-pound RC model shown in the video above proves to us that Challis has a good chance of delivering on its ambitious goals for its aircraft. To bad the RC model isn’t available for purchase, or it would be at the top of our holiday wish list.

    This device is NOT a tilt-rotor as the title implies. Even the company website states that it is a challenge to tilt-rotor technology.

    It’s still more complicated than a helicopter (adds a front propeller/engine) but it does look like it would be simpler to build than a tilt-rotor.
