Project BAT[/heading]
On the project BAT worked in the mid-nineties of the last century at the Research technical institute of ground forces in Vyškov group led by the colonel. Ing. Ferdinand Jurčou. Its task was to develop and fabricate a prototype of the device for the training of specialists analyzes the image information to the PC drone of SOJKA-III/TV and for the implementation of the artillery air reconnaissance. The ensemble was perfectly simulate the operation of the drone of a blue JAY when using a surveillance television camera. For unmanned means of a blue JAY should be in this way prepared attendants and specialists for evaluation and processing of information. Complete loadout artillery air reconnaissance BAT should provide a survey to the tactical depth of artillery of volumes of the adversary and his staff for the direct management of the artillery fire. Using other developed ancillary facilities (vaguely) was used to survey the marching of the os, checks the effectiveness of its own camouflage equipment, courier service, or to transport, and planting of parachute airborne special forces.
In the years 1995 and 1996 the project was a BAT from the state budget released amount of 18.7 million Rubles.
Komplet BAT should consist of the following parts:
- Light reconnaissance aircraft
- Ground control stations (workplace specialist analysis of image information - consistent with the workplace drone of a blue JAY)
- The workplace for preparation and management of flights, and for the evaluation of the artillery air reconnaissance
- Shipping and odsunové mobile devices
- Reconnaissance and search mobile resources
- Equipment crews of a light reconnaissance aircraft
a Light reconnaissance aircraft an ensemble of a BAT it was basically a two-seater motorized hang glider, simple maintenance and handling.
Skeleton the supporting area should be light and sufficiently rigid with the operating multiples of +4g and -3g. The cover should be lightweight with a reinforced leading edge and struts over the entire length of the profile. The construction of load bearing surfaces should allow ease of handling when folding and unfolding.
three-Wheel undercarriage had during an emergency landing to absorb the energy with a forward load 4 - 5g, and 2 - 3 g in the vertical direction. He had to allow the installation of television system SOJKA-III/TV with radio transmission and radio navigation system including GPS. The dashboard should include a speedometer, altimeter, vertical speed indicator, compass, tachometer, fuel gauge and on-board clock. Diameter of bogie wheels should make it possible to conquer the terrain shape up to 15 cm high. The chassis should have braked the front wheel, a shock absorber and should permit an easy replacement of the wheels for the skis.
Fuel system should form a certified engine power 36 kW with a reducer and a pusher propeller with a minimum static thrust of 1400 N. The power system should have a small emissivity in the infrared spectrum and be capable of launching during the flight. The fuel tank should have a volume of 32 dm3.
Rescue system formed a parachute with an appropriate control mounted in the container and had a maximum weight of 12 kg. The maximum speed of descent should be within 6m/s.
Radio with minimum weight and dimensions should comply with the conditions of ICAO, should have its own power supply, should be resistant to interference. The minimum reach from the height of 300m should have been in the rugged terrain of 15km.
