MK5 Description

The scope of duties of this amphibious airplane is the applicability, to make extensive use of a light cargo amphibous aircraft. Multifunctionality, simplicity,multiability special STOL (low and high speed can be reach due to special arrangement and construction of the wing and stabilizer); WIG; amphibious; long range; cost effective production price due to simpler structures and interior aeronautical systems; low visibly properties (nose and centroplan shape and shielding engine outlet-gas exhaust, low vulnerability; survivorbility due to rescue parachute system; There is no need expensive hydraulic control system.

MK5 Military Description

The primary consideration of utilization of designers was the light special military cargo amphibious airplane. The crew consists of one pilot and one copilot operator for board defense guns and for navigation proposition, and the airplane can carry six fully armed soldier. The airplane has a mounted board defence machine guns (two piece M134 multi barrel minigun system with with 2*3000 rounds of ammuntion) and anti aircraft air to air defense missiles (four pieces AIM-92 Stinger). The selected engine is the powerfull up-to-date Honeywell TPE-331 -12 UHR turboprop with 1100 shp power. Infrared signature of engine exhaust also reduced due to empegnage arrangement and special shape of exhaust.
