Short
presentation of the MAV.
Classic flying wing
structure.
The vehicle airframe
use the latest COTS equipment, exploiting technology advances
in miniature brushless motors and Li-Po power cells to provide
an initial endurance in excess of 22 minutes. With further airframe
optimisation we expect to achieve in excess of 30 minutes, all
from an airframe costing under £150 in component costs.
CAD/CAM technology is used to design and manufacture the airframe
using advanced EPP foam materials and hot wire cutting machinery.
The objective is to develop the processes to enable rapid prototyping
of payload or mission specific vehicles.
Marginal fixed
rudders. Commands on 2 axis : elevons coupled for elevator and
roll. All structure made in Expensed Polypropylen (EPP). Servomechanism
and receiver from modeller technology . Propulsion using modeller
brushless outrunner motor (Microtex 20/5/14, manufactured from
FreeAir (Cz)) Propeller APC. Lithium Ion Polymer batteries (2
series 900 mAh). Human remote control flight.
In preparation :BBS
have prototyped the miniature Surveillance autopilot system,
SNAP, which includes a full set of miniature sensors, featuring
gyros, accelerometers, barometric and dynamic pressure sensors,
temperature sensor and GPS interface. The autopilot is equiped
with a powerful single board computer running a full Linux operating
system, enabling user developed complex control systems to be
run. We believe that at just 100x40x15mm and 34g, SNAP could
be the smallest autopilot in the world with this degree of processing
power.
