1Purchase of two UAVs is recommended for continuous surveillance – the second aircraft is launched immediately after landing of the first one. The UAV can be supplied with additional replaceable accumulator batteries.

Flight modes:

  • manual;
  • automatic with fulfilment of programmed functions;
  • automatic return along the previously programmed path;
  • sighting of the survey target;
  • circling around the set point;
  • wind speed measurement;
  • pitch-down.

The power unit is driven by an electric motor with a pusher screw.

Take-off is performed from technically unprepared sites using a low-pressure pneumatic catapult.

Landing is performed using an onboard parachute.

UAV T28 fulfils the following functions:

  • optional transmission of video or thermal image of the survey target, current coordinates, flight height relative to the start point, flight speed, flight course angle, UAV’s distance from the start point, and other required operating information via radio channel to the ground control panel (GCP);
  • folding for transportation and unfolding for flight without tools;
  • replaceability and quick removal of the modular payload and dismountable components without adaptation;
  • acoustic invisibility.  

The UAV is equipped with a flight data dynamic forecast system. Navigation is enabled by GPS\GLONASS and magnetic course system. UAV Т10 is equipped with radio controlled LED lights in wing panels and rear fuselage. Control channel is digital. Operating frequency range is 902-922 MHz. UAV design provides for simultaneous installation of photo, video and thermal imaging onboard cameras .

Replaceable modular payload

Eleron-3SV system includes two unmanned aerial vehicles Т28 with installed payload modules.

Composition of UAV No. 1 modular payload:

  1. Gyro-stabilized payload mechanism with 3-axis control, equipped with a 10x optical magnification-enabled video camera.
  2. Digital photo camera with minimum 10.2 mpix resolution.

Composition of UAV No. 2 modular payload:

  1. Combined gyro-stabilized controlled payload mechanism equipped with 10x thermal imaging and video camera. The thermal imaging camera is based on an uncooled microbolometer with resolution of 640×512 pixels.
  2. Digital photo camera with minimum 10.2 mpix resolution.

Additional payload:

  • drop containers (optional),
  • weather balloon (optional),
  • transmitter (optional),
  • gas analyzer (optional)
  • other payload at the customer’s request.

Electronic catalog of onboard modules

Ground control panel

GCP is based on a portable computer with moisture and dust protection, receiver-transmitter unit and antenna-feeder system.

GCP fulfils the following functions:

  • UAV control in all flight modes;
  • positioning of onboard video and thermal imaging cameras;
  • displaying electronic map and video/thermal image of the survey or photoshoot target received from the UAV;
  • displaying the electronic map of the UAV flight route and its current coordinates (geographical and/or orthogonal in SK-42 system with an option of quick transfer from one system to another);
  • displaying the survey target coordinates (geographical or orthogonal with an option of quick transfer from one system to another);
  • displaying the UAV flight mode and engine operation mode;
  • displaying the UAV battery charge and estimated remaining time of flight;
  • displaying the UAV flight height and speed;
  • displaying the UAV distance from the start point;
  • recording of information received from the UAV (video stream and screenshots with gridding);
  • play back of the recorded video information at reduced or increased speed in the screenshot mode with the possibility to zoom in on screenshot parts;
  • displaying the current time (hours, minutes, seconds);
  • flight assignment preparation based on altitude map.

GCP design provides for both wireless and wire connection of the portable computer with the receiver-transmitter unit and the antenna-feeder system.

GCP design provides for transmission of the information to external devices via video outputs and ETHERNET.

Control failure protection is enabled.

GCP weight is maximum 12 kg.

GCP is compatible with all systems of Eleron family.

Launching devices

Eleron-3SV is supplied with a launching device (pneumatic catapult).

1. Rubber-rope catapult

Rubber-rope catapult comprises a rubber rope with fastening hook and extension length limiter and is placed in a fabric case. The extended rope length is 18 meters. Weight: 3.8 kg. Length: 10 m. Maximum tension load: 23.5 kgf.

2. Pneumatic catapult

The pneumatic (mechanical) catapult is a pneumatic cylinder located inside a receiver and equipped with a pusher. The pneumatic power converts into forward movement of the pusher, giving an initial impulse to the UAV. Automotive compressor for tire inflation is used for pressure generation in the receiver.

Technical specification of the pneumatic launching device:

  • operating pressure of the receiver: 1.0 MPa;
  • dimensions in operating state: 2.9×0.78×1.1 m;
  • dimensions in transport state: 1.62×0.19×0.3 m;
  • launching device weight: 15.2 kg;
  • compressor weight: 4 kg.


The pneumatic catapult is stored and transported in a plastic container which is convenient to carry.
