Design and development
editThe CoAX 2D/2R was originally known as the FLIP 2 (Fly In Perfection) and is a derivative of the FLIP 1, a conventional helicopter with a main and tail rotor.[1]
The CoAX 2D/2R was designed to comply with the European Class 6 microlight helicopter rules, including the category's maximum takeoff weight of 450 kg (992 lb). Design testing commenced in 2012.[1] The newest version of the helicopter, CoAX 600 has an increased mmaximum takeoff weight of 600kg. This is aligned with the changes in the German regulations for ultralight rotorcraft.
The design features dual coaxial main rotors, a two-seats-in side-by-side configuration enclosed cockpit and skid landing gear with ground handling wheels. The two variants use different power plants. [1]
The aircraft fuselage is made from composites. Its dual composite two-bladed main rotors have a diameter of 6.50 m (21.3 ft). The aircraft has a typical empty weight of 283 kg (624 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 167 kg (368 lb). With full fuel of 48 litres (11 imp gal; 13 US gal) the payload for the pilot, passengers and baggage is 132 kg (291 lb).[1][2]
Variants
edit- CoAX 600
- Current production version in 2025, powered by a six-cylinder, air-cooled, four stroke 160 hp (117.7 KW) ULPower UL390iS engine. This version has a maximum take-off weight of 600kg, complying with the new ultralight regulations in Germany. [3]
- CoAX 2D
- Current production version in 2017, powered by a six-cylinder, liquid-cooled, four stroke 135 hp (101 kW) D-Motor LF39 engine.[1]
- CoAX 2R
- Version powered by a four-cylinder, liquid and air-cooled, four stroke 100 hp (75 kW) Rotax 912ULS engine. No longer advertised as available in 2014.[1][2]
- CoAX 600 UAS (Unmanned Aerial System)
- An unmanned version of the CoAX 600 was developed in a research and development project by edm aerotec GmbH and the Technical University of Munich. CoAX 600 UAS obtained a permit-to-fly from the LBA via the SORA process and completed successful flight testing at the Magdeburg-Cochstedt Airport (EDBC). [4]
