presentation of the MAV.
A four flapped wings
model with high quality flying.
All wood and mylar
The wings are powered
by a motor that weighs 2 grams producing a power output of about
1W. It is in fact a motor that is used in mobile telephones.
This motor feeds into a gearbox that reduces the rotational
velocity of the engine. From the gearbox a z-shaped axis rotates
at the reduced rotational velocity.
this axis, at two different locations (related to the phase
of the wings) two ‘conrods’ are placed that are
themselves connected to the wing spars which provides the flapping
Riding at the very
front of the Delfly is a micro colour camera of about 1 gram
that is capable of real-time streaming of images back to the
‘ground’. In order to get rid of noise on the video
signal one connects the transmitter, camera and motor to three
separate batteries. The motor and transmitter are fed by 140
mAh and 90 mAh lithium polymer batteries. The camera is fed
by another 90 mAh battery as well as another unidentifiable
power source (Dutch national security concerns). This configuration
not only minimises noises but also increases the flight endurance
to at least 16 minutes.
Motor and gear equipment
are Didel Products.
