<\/a>Considering the reduced size of the vertical tail fin, we can assume that the aircraft will not use aerodynamic forces at high speed to counter the torque from the main rotor. Using aerodynamic forces would help reducing the use of the tail rotor, thus providing more power to the main rotor. However, this would need a bigger, thus heavier tail fin.<\/p>\n
The single-engine helicopter is tailored for heavy duty in the mountains, not for high speed records.<\/p>\n
The cockpit provides a great visibility of the surroundings, including below the aircraft, thanks to the transparent floor.<\/p>\n The differences between the two prototypes are very subtle on the photos. The first noticeable change is on the landing skid, where a strut was added at the back. Other changes have been made on the roof, between the rotor mast and the engine. The fire protection has been removed or, at least, reduced in size. Additionally, the structure strut beside has received a nice fairing. Also, the rotor mast is now equipped differently.<\/p>\n Marenco Swisshelicopter released a video of the first flight of their second prototype HB-ZXB piloted by Richard Trueman, Chief Test Pilot, and assisted by Peter Wittwer as Flight-Test Engineer. The flight was performed on February 26th 2016 at Mollis airport in Switzerland. https:\/\/www.youtube.com\/watch?v=jtYNBzIPoMc Considering the reduced size of the vertical tail fin, we can assume … Continue reading SKYe SH09: 2nd prototype flying<\/span> <\/a><\/a><\/a><\/a>
