The DTA J-RO (transl. gyro) is a French autogyro designed and produced by DTA sarl of Montélimar. The aircraft is supplied complete and ready-to-fly.[1]
Design and development
[edit]The J-RO was designed to combine the advantages of an ultralight trike with an autogyro. As such it is a "Cabriolet" (convertible) design whereby the gull-winged doors are removable to allow open air flight in the summertime and an enclosed cockpit for cooler weather. The doors are a factory option and may be purchased and installed later.[1]
The design features a single main rotor, a two-seats-in tandem configuration enclosed or open cockpit with a windshield, tricycle landing gear with wheel pants and a four-cylinder, liquid and air-cooled, four stroke 100 hp (75 kW) Rotax 912ULS or turbocharged 115 hp (86 kW) Rotax 914 engine in pusher configuration. It has a Kevlar belt-driven pre-rotator for the main rotor.[1][2]
The aircraft fuselage is made from carbon fiber reinforced polymer. Its two-bladed rotor has a diameter of 8.60 m (28.2 ft) and a chord of 21.3 cm (8.4 in). The aircraft has a typical empty weight of 282 kg (622 lb) and a gross weight of 560 kg (1,235 lb), giving a useful load of 278 kg (613 lb). With full fuel of 68 litres (15 imp gal; 18 US gal) the payload for the pilot, passenger and baggage is 229 kg (505 lb).[1]
In noise testing for acceptance in Switzerland the design produced 62.4 dB. The Swiss testing requires the design produce no more than a maximum of 65 dB for this class of aircraft.[2]
