WHT coaxial rotor system helicopter
The CoaX 415T 5-seat helicopter is one of the models under development
Helicopters featuring coaxial rotor designs are not exactly new. The co-axial design of a pair of rotors mounted on the same mast and with the same axis of rotation, but turning in different directions, has been utilized on a number of military helicopters for around half a century, most notably those produced by the Russian Kamov helicopter design bureau. The coaxial design offers a number of advantages over the traditional helicopter designs, which makes it difficult to understand why we haven’t seen co-axial rotor designs taking to the skies for civilian uses. Now Australian based Wieland Helicopter Technologies (WHT) is hoping to change that by designing and manufacturing a range of new coaxial rotor system small format helicopters for commercial markets.
