SELF VENTING ENGINE COMPARTMENT
One of the early and still a problem with
the Canard type Pusher aircraft, Cozy included, is the confined space between
the firewall and the forward engine baffle. This space tends to retain
heat and could damage the Mag. coil and possibly other electronic
components you may have installed in that area , after you have landed
the aircraft. If you notice on a canard gathering oil dip stick door
is left open on the aircraft cowling. Nat suggested a vent right up on
the top of the top cowling. This vent will stay closed in flight but a
soon as you land and park the door will open and let the heat out. But!!
with the door open you have created another problem "RAIN" for Mag equipped
engines a water logged Mag. coil is not desirable either, so what to do?
Here is one solution!! I bought a VolksWagen "Bellows" thermostat the one
that controlled the vent to the big fan housing in the VW engine, I mounted
this bellows on the firewall and
made a lever that is rigged to lower when the thermostat expands, thus
opening the vent. The vent will stay open for one hour.
