Mini-Reis: Timeliness of the Project

At present, Ukraine does not have:

• aircraft false targets (imitators) to enhance the efficiency of aviation in case of active air defense of potential adversaries

• air targets to train air defense personnel

• effective means for air reconnaissance in an operation and tactical area

• effective means for destroying tactical and strategic unmanned aerial vehicles (UAV) and remotely-piloted aerial vehicles (RPAV) of potential adversaries

Mini-Reis UAV family: project objectives

The project provides solutions to the existing challenges in Ukraine by developing a family of

multifunctional unified light jet UAV (and a set of equipment based on its technology) that would

provide for:

defending the activities of front-line aviation with a help of light jet UAV as false targets

(imitators) and generators of radio and infrared interferences

training personnel of air defense facilities to use UAVs as aerial target

performing reconnaissance (visual and radio-technical) in a tactical and operation area

performing highly accurate attacks and destroying small-sized targets using warheads on

board of UAV (miniature cruise missile)

performing highly accurate attacks and destroying reconnaissance tactical and strategic

UAVs of potential adversaries (UAV fighter based on the proposal developed by SRI PFM

KhAI, Kharkiv and Donetsk, under the title “Grif-Vulture” ).

Mini-Reis multifunctional family

UAV usage:

single use with potential self-destruction

multiple use – returning and parachute landing on inflatable shock absorbers

UAV base variants:

air – external loads (up to 6) on a mother aircraft and air-based control station in a secondary

cockpit

land – stationary and mobile on vehicle chassis with a land-based control station

sea – with a ship-based control station

UAV launch variants:

air-launched from external load sling of a mother aircraft

jet-propelled from a launch container (incl. mass launch for a group usage up to 32 at a time)

from a stationary or mobile pneumatic catapult

Mini-Reis modular primary and secondary payload

Mini-Reis nose section can accommodate:

Luneberg lens, generating radar cross section levels imitating aircrafts

digital panoramic air cameras for optical reconnaissance in visible and infrared bands

infrared and radiolocation target search and homing

other equipment

Mini-Reis center section can accommodate:

chaff and flare dispenser

radio electronic equipment of staging imitation and noise interferences for air defense systems

radio reconnaissance station for recording emissions of SAM radio location stations and sending commands on targets

radio equipment

supplementary fuel tank

parachute landing system

warhead

other equipment

Mini-Reis tail section can accommodate:

heat imitators (IR-tracers)

smoke generators (smoke tracers)

Mini-Reis family unified components

• single aerodynamic scheme with similar key parameters (lifting surface loading, thrust-to-weight ratio) that cuts down expenses and time on aerodynamic tests

• unified components of onboard equipment

• single air-based control stations

• single land-based control stations

• single ship-based control stations

Specific aerodynamic concept of UAV family

• integral aerodynamic layout of an aircraft with a bearing body, thathas strakes in front of a wing to achieve "vortex“ aerodynamic effects

• ease of folding the wings to place UAV in a launch container and asexternal load on a mother aircraft

• flat forms of UAVs (surfaces of small curvature)

• conformal high-mounted air intake of a power unit of the recessedtype, gas dynamically integrated into the aircraft carrier system

• relatively small specific load on lifting surface area

• relatively high weight-to-thrust ratio

• a nozzle of the motors ejecting incoming air for shielding noises andIR radiation

This specific aerodynamic concept provides for:

• high aerodynamic properties with a smaller lifting surface

• high maneuverability

• low visual, thermal and radar visibility while complying with therequirements for basic flight performance
