Unmanned Aircraft Complex «chizh-l»

Unmanned Aircraft Complex «Chizh-L» on the generally accepted classification of military Unmanned Aerial Vehicles (UAV) belongs to the class of tactical short-range systems to meet the requirements of aerial surveillance, reconnaissance and target designation. For the Military 
purposes can be used as part of the intelligence information systems the company, battalion 
and an artillery battery level.
When designing the complex originally envisaged the possibility of its limited use in the open air space for the action of special units to meet the challenges of aerial surveillance in emergency management, supporting counter-terrorist, security and search operations.

Specification of the complex «Chizh-L»:
• modularity of the aircraft and payload - 7 basic options of payload;
• simultaneous synchronous flight (formation) up to 4 UAVs;
• modularity and high mobility of complex;
• all-season, 24-hour, off-airfield;
• the possibility of flights to areas with difficult terrain (mountains) and over the sea (take-off and landing on a ship);
• high availability of complex systems;
• redundant radio channels to UAV (VHF range and satellite system «Iridium»);
The unmanned aerial vehicle has a modular design. It’s made of composite materials to provide low visual, acoustic, thermal and radar visibility. The power plant is based on 2.5 hp twostroke piston engine UAV flight can be performed offline on the programmed route within a radius of 200 km from the ground control station or in real time within a radius of 50 km in the mode of remote management 
and control.
The entire complex, including ground support equipment are packed in compact containers for the transportation, which ensures a maximum mobility when using any type of transport.
The complex is easy to maintain, can be applied to unprepared terrain and does not require special infrastructure.

Complex structure
• UAV (from one to five) in shipping containers;
• Ground control and surveillance station in a secure briefcase:
• Ground radio terminal;
• Ground power supply system;
• catapult launcher;
• Set of spare parts and auxiliary equipment.

Complex functioning
The operation of the complex is supported by (he team of four: a pilot-operator, a video surveillance operator, a mechanical engineer and an electronic equipment specialist. Deploymenttime of the complex for the start position does not exceed 30 minutes.
The aircraft takes off from a catapult launcher and performs the parachute landing completely automatically. The onboard computer manages the autonomous aircraft return in case of the command channel failure as well as the automatic emergency landing in case of a critical system fault, which assures the safe flight.

UAVs payload.
High-resolution color video camera, digital photo camera, infrared camera, video channel transmitter with antenna. The entire payload is placed in an easily replaceable nose module thatprovides different configuration options to broaden the scope of mission tasks.

The on-board computer system.
Provides an automated control, navigation, management and diagnostics. It is based on the inertial navigation system with a GPS correction. The UAV is either controlled by a preprogrammed set of three-dimensional waypoints, or switched into a semiautomatic mode to be controlled from the ground.

The ground Control Station.
Provides mission planning, preflighl on-board and ground systems diagnostics, aircraft equipment monitoring, (light and payload control, receiving and processing the surveillance video and photo data. Two operators manage up to four aircraft simultaneously.
