PCHELA-1 RPV-ASSISTED
AERIAL SURVEILLANCE SYSTEM
The Pchela-1 remotely piloted vehicle (RPV) is intend-
ed to conduct aerial reconnaissance within the tactical
operations depth. The RPV can also be employed for
traffic, gas and oil pipeline patrolling, power transmis-
sion line servicing, and for-
est fire detecting.
The system comprises:
- Pchela-1 RPV;
- launch and control station
mounted on tracked chassis;
- mobile maintenance station.
The RPV has a normal aero-
dynamic configuration with a
high-mounted straight wing.
For roll control, the wing is
provided with ailerons.
When shipped, the wing
panels are folded one under
another along the fuselage.
The vehicle’s tail unit is annular-type and comprises a
pusher propeller and fully rotatable elevator and rudder.
The Pchela-1 RPV is powered by a piston engine
installed in its tail portion.
Composite materials are used in the RPV structure. The
landing gear of the RPV has four non-retractable struts
capable of withstanding a ten-fold vertical g-load.
The onboard reconnaissance equipment comprises
a TV camera or infrared sensor mounted on a gyro-
stabilized belly platform. The TV camera is provided
with a variable-focus lens enabling the operator to
change a vision angle within the range of 3 - 30 deg.
The infrared sensor’s field of view is three quarters
of the flight altitude, and its resolution is 3 mrad.
The flight stability of the RPV is ensured by an autopilot.
The RPV is launched from short guides by means of
two solid-propellant boosters.
The RPV uses a parachute/shock-absorber system for
landing.
The launch and control station makes it possible to
carry out a prelaunch automatic check, launch and
flight control of the RPV, reception and display of a ter-
rain picture on the TV screen in real time. A video mon-
itor displays the terrain picture, as it viewed from the
RPV, as well as the superimposed flight route and cur-
rent position of the vehicle. The station can control and
receive information simultaneously from two vehicles
located up to 60 km away.
