LOOP News 9 OCT 07: BACK IN THE U... UKRAINE!The company was set up eight years ago to design and build a new light helicopter, with the prototype making its first flight in 2001, and a second, improved version two years later. Ukrainian type certification was achieved last year, and the factory says the aircraft conforms to US FAR Part 29 airworthiness regulations. EASA type certification is being sought, and the helicopter is on sale already in the USA, South Africa and parts of Europe as an 'experimental' aircraft. Engine for the AK1-3 is a Subaru EJ-25 petrol car engine with a liquid cooling system. The flight controls have mechanically linkages; the collective and cyclic pitch control is through a push-pull control linkage as is the tail rotor. "Employment of a main rotor with a flexible (torsionally-soft) attachment of blades has enabled a considerable control augmentation and improvement of the helicopter manoeuvrability," says the factory. "High manoeuvrability is also ensured by a low-disc loaded rotor, high power-to-weight ratio, moderate moments of inertia and a sufficient margin of control." The light weight of the AK1-3 has been achieved with extensive use of titanium and carbon-fibre composites. Production of the first 15 aircraft is now underway at Aerokopter's 1200 sq metre factory.
