Dornier mini telecopters
The Mini-Telecopter II (MTC II) was an unmanned helicopter with a coaxial rotor made by Dornier , which flew remotely via a cable in 1981 and was later to be controlled free-flying via radio. The device was designed as a sensor carrier for tasks in the army and navy . It was the successor to a smaller MTC I experimental unit, the trials of which began in mid-1970. Dornier ran this program from 1975 to 1995 with self-financing.
description
For this aircraft, Dornier used the development of Alfred Vogt, under whose direction Wagner Helicopter Technik developed the Sky-Trac helicopter series and later the successor Skyrider at HTM. Vogt, who had set up his own business at Wagner after setting up the programs, also supplied the aircraft, while Dornier developed and installed the stabilization and controls and took over the testing. Dornier, who also led the larger Seamos development at the same time , saw the MTC II as an addition to their drone program for reconnaissance, target location and fire control. The device flew in 1981, with the control signals still being transmitted from a ground station to the flying device via a detachable cable. There was no longer any radio-controlled free flights because Dornier was integrated into DASA and the activities of the von Vogt company collided with the interests of the DASA helicopter division. The program was discontinued in 1995.
The design feature was a counter-rotating coaxial rotor with 2 × 3 rotor blades and 3.2 m diameter. The "hull" was designed as an open equipment carrier for a two-stroke engine with 40 hp from Hirth, tank and control stabilization systems. Take-off and landing took place on four stilt legs. With a take-off mass of 190 kg and a payload of 60 kg, a flight endurance of 2 hours and an altitude of 1000 m could be achieved.
