The project is based on the task of improving of working conditions of onboard observation equipment of two-engined unmanned aircraft. The aim of the project is increasing the limits of front hemisphere observing and reducing of vibration load on the specified equipment.

M-7D "NEBESNIY PATRUL" is a twin-engine aircraft of normal aerodynamic scheme with high located wing. The plane is made mainly of composite materials using wood and metal. Upper front and rear part of the gondola are made in the form of movable fairing for access to the payload bay. Gyro stabilized full CCD – camera is the standard payload.
