1. Description and Operation
A. Description
(1) The Trakkabeam
®
A800 airborne high intensity searchlight represents the latest in design and
development for this type of system. The searchlight can be mounted to the helicopter external
structure at any suitable position required by the operator but with reference to the Installation
Manual.
(2) The searchlight system consists of the following major assemblies:
(a) Gimbal/Lamp assembly (PN 200003-XXXXXXX).
(b) Power Conditioning Interface Unit MKII (PCIU) (PN 011012-XXXXXXX).
(c) Control Interface Unit MKII (CIU) (PN 091016-XXXXXXX).
(d) Trakka Control Panel (TCP) (PN 021019-XXXXXXX)
(e) Grip Hand Controller (PN 021012-XXXXXXX).
NOTE: Assemblies that are provided with different options are identified with part
numbers consisting of ‘base number-XXXXXXX’. Part numbers will be shown
in this way throughout the manual where they apply.
(3) Gimbal Assembly.
(a) A two axis gimbal providing both azimuth and elevation tracking is controlled by using either
one or two grip hand controllers which can be integrated with a camera system using RS422
or RS232 slaving. The main assembly utilises a worm gear and brushed DC motors together
with a simple position encoder to control each axis. All control electronics are located in the
PCIU MKII.
(b) Searchlight movement is software controlled for both elevation and azimuth to prevent
operation in unsafe regions on the aircraft. In the event of system failure, mechanical hard
stops provide a safety backup to stop movement of the searchlight.
(c) The lamp assembly consists of an 800W lamp and up to six optional filters (including IR) with
zoom capability. The light source is a short arc xenon type operating off a 12-24VDC
regulated (power controlled) supply located in the PCIU MKII.
(d) The unique Trakkabeam
®
quartz optical elements focus a high energy light beam with energy
spreading evenly from the centre to the outside edge to ensure the best possible search
capability while an integrated optical filter system provides a maximum of six different
coloured light beams, including infra-red. The filter elements are easily selected during flight
via the grip hand controller.
(e) When first turned on, the A800 system performs diagnostic and alignment checks in both
azimuth and elevation to find the travel envelope and when finished, will return to a pre-
defined position.
(f) The basic system layout for the A800 is shown in Figure 1 and Figure 2. These illustrate the
primary system components as well as the optional secondary grip hand controller which may
be built into the cyclic, collective, or other suitable control point inside the aircraft.
