AC5-MP – a single-seater motor-glider and has been equipped with an engine: Rotax-912UL2, capacity 80 h.p., four-cycle, is established on a immobile pylon. This engine allows to achieve height of flight more than 6000 m.
The given pre-production model has been designed and made in 2003. Flight tests of the prototype have been carried out in August – October 2003. One specimen of AC5-MP for use has been made as unmanned flying vehicle and carrying out for scientific researches in one of the Russian scientific research institutes. АС5-МР is a single-seater airplane with the small fuel consumption. The fuel rate: 6 litres per 100км at speed of flight 120 km/h. Duration of flight can be increased up to 12 hours and more after rigging out with additional fuel tanks. This motoglider can be applied for monitoring or for business flights. Installation of more powerful engine (100 h.p. or 115 h.p.) as a customized option is possible. This flying vehicle may be easily done disassembled or rigged. While assemblihg the glider: connections of ailerons, joining of interceptors and an elevator – are produced automatically. This motoglider can be transported in a special trailer with the help of an automobile. The same trailer can be used as a small hangar.
AC5-MP was designed on the basis of airframe AC-5M. On a fixed pylon four-stroke engine Rotax-912 UL2 by power 80 h.p. is established. It is a single-seat airplane with the small fuel rate, and it is intended for unmanned flight to produce a middle-altitude mission (from 400 m up to 8000 m) of round-the-clock patrolling or atmospheric probing. On the ship was nested the onboard navigating system including a complex of the integrated inertial and satellite navigating system, the radiocommand channel of flight control, TV system of monitoring, and also the equipment of automatic dependent supervision.
The aerodynamic scheme of the plane allows, if a stop of the engine has occurred, to switch powered flight to a glide slope regime with rate of sink of 1.5 m/s. Air brakes provide gaining accuracy of the landing and to make a landing more safe, and also gives a normal completion of flight in a sudden failure of the engine.
