This section provides further information about each of the subsystems incorporated
in PRISM RPAS. The functionality and operation of each sub system is detailed in the
following sections.
More information about the maintenance of each subsystem is provided in
Chapter 10
.
The Airframe consists of a central, octagonal body that houses the flight control system,
communication systems and power systems. Each of the 4 boom arms are connected
to a corner of the body via a folding/locking mechanism that allows the booms to fold
sideways against the central body for transport and storage. The booms are locked into
position during flight with a spring loaded pin system.
The Central body is constructed from flat carbon fiber sheets, affixed to each other with
several vertical aluminum bulkheads. This creates the rigidity in the body required to safely
handle forces and loads experienced during flight.
PRISM features a sturdy 12mm carbon fiber rail system which is securely mounted to
both the top and bottom of the aircraft. This 12mm rail system may be used for mounting
battery tray(s), payloads and other accessories.
The Flight Battery Tray attaches to the top or bottom of the airframe, sliding into position
where it is secured onto the 12mm rail system. A total of four bolts must be tightened in
order to ensure the battery tray is securely attached to the 12mm rail system.
PRISM uses T-shaped landing gear constructed from carbon-fiber rods that attach
firmly into receptacles built into the underside of the central airframe. These have been
constructed to provide adequate ground clearance for mounting a range of payloads
beneath the airframe without adding significant weight to the MTOW. These landing gear
are 30mm in diameter and when installed, offer a ground clearance of 12”. If a higher
ground clearance is required, please contact Watts Innovations support to request a longer
landing gear set.
PRISM can be configured to operate with payloads which may use alternate landing
gear. When using these payloads, the PIC must account for deviations from the
manufacturer-defined weights and balances.
