UAV
The Munin A20 UAV has a long range and 48 hour endurance. It is intended
to fulfill a number of roles in both civil and military markets.

Stretcher bridge for aero-medical helicopter
The bridge was designed to allow paramedics to mount all of their first
responder medical equipment within easy reach, while allowing them to give
their full attention to the patient. The bridge had to satisfy the needs
of the paramedic and comply with various air-worthiness and crash-worthiness
requirements. Click image above or

Manually pitch adjustable propeller for 100 HP aero engine
The manually adjustable propeller was designed to be fitted to the
Rotax 912 gearbox aircraft engine. The first prototype was tested to a
propeller tip speed in excess of Mach 1.
Electrically adjustable propeller for 300 HP aero engine
Initially an upgrade from the 912 prop, the electric propeller was
redesigned substantially. It features a double earthed, dual electrical
system, reversible pitch with a mechanical and electrical interlock to
prevent runaway. The entire prop can be dismantled while remaining on the
aircraft, allowing easy blade change or drive mechanism change.
In-Flight Adjustable propeller
The in flight adjustable prop was designed to be installed on a 300
hp automotive engine, for installation in a high performance sports aircraft.
It features all carbon blades with densified wood cores and a single billet
hub construction. Each blade can be replaced as a stand alone item.
All blade bearings can be removed without removing the prop from the engine.
Electro mechanical pitch adjustment through a full range, from feather
to reverse, is available. Reverse has two interlocks intended to prevent
inadvertent reverse selection. A fail-safe 'return to flight pitch' mechanism
is also built in, allowing normal flight if electrical control of the propeller
is lost.
Creative Cad designed and built a two blade and three blade hub mechanically
controlled hubs, both of which were built in house and successfully ground
run. The two blade hub was also test flown to a tip speed of 0.95 mach.

Retractable main landing gear for light aircraft
Conceptual design for retractable landing gear on a light aircraft.
Gear has been designed to be retracted using a single linear actuator,
with a free fall 'emergency' extension should electrical power fail. The
system uses a cable and gas springs to unlock the up locks, and the gear
motor and a small hand activated winch provides a back up to fully extend
and lock the gear if aerodynamic loads prevent the free fall system from
working completely.
Visual tabs, consisting of mechanical indicators are exposed above the
wing when the gear is fully locked down. Gear doors are mechanically driven
to automatically follow the gear during extension/retraction. The gear
has to rotate by a few degrees during retraction to better fit into the
minimal space left within the wing.
Instrument panel
Creative CAD has designed and built several instrument panel systems
for the Jabiru Aircraft. Panels are CNC cut and engraved and an easy to
follow and reliable wiring process replaces the factory system.
Gee Bee Cowl
A refreshing break from CAD and machining, the Gee Bee cowl was designed
and built in house, using in house developed equipment and skills. The
cowl is installed on an experimental aircraft intended to be a 'stand off'
scale version of the 1930's racing aircraft.
Stretcher lifter for air ambulance
The stretcher lifter was designed to suit an aero-medical operator
who had smaller aircraft than the norm. The lifter is placed under a false
floor and can be easily extended. Once extended two legs fold down and
lock the lifter in place. The table then descends, driven by a linear actuator,
the table accepts the helicopter instrument flight simulator.
Helicopter container transport rig
The rig was designed to accommodate a Dauphin helicopter that had to
return to the manufacturer for a major repair. The prohibitive cost and
time delay for using the factory transport rig, plus the need for the factory
unit to use an open container, drove this project. It was completed in
three weeks and at about 10th the cost of the factory unit.
Aside from being a container rig, the rig was fitted with casters and
with telescoping legs fitted the aircraft landing gear attach points, allowing
the strongest part of the aircraft to take transport loads. The rig also
allowed the repair work required to be carried out without having to to
remove the helicopter from the rig.
