DTA J-RO

The DTA J-RO is a French autogyro designed and produced by DTA sarl of Montélimar. The aircraft is supplied complete and ready-to-fly.

Design and development
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.

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 Rotax 912ULS or turbocharged 115 hp Rotax 914 engine in pusher configuration. It has a Kevlar belt-driven pre-rotator for the main rotor.

The aircraft fuselage is made from carbon fiber reinforced polymer. Its two-bladed rotor has a diameter of 8.60 m and a chord of 21.3 cm. The aircraft has a typical empty weight of 282 kg and a gross weight of 560 kg, giving a useful load of 278 kg. With full fuel of 68 L the payload for the pilot, passenger and baggage is 229 kg.

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.
