2. »Investigate materials and develop
systems to protect a small recon-
drone from fire and heat
damage, so that such a device
could be used to help with urban
firefighting in the future

3. » Used in searching buildings during firefighting
operations
» Enters interior of upper floors by breaking a
window
» Complete all primary and secondary searches in
less than 73 to 42minutes

» Firezed Heavy Duty came in second
» AS2400 looses rigidity when heated, leading to
very poor performance in this test rig
» There is substantial noise in the data

20. » Use Nickel metal-hydride batteries,
NOT LITHIUM POLYMER BATTERIES
» Aluminum propeller blades would probably suffice
for this drone’s needs
» If there is a chance to redo this, do it inside and
with a more controllable heat source
» A future test should involve flying helicopter and
Quad-copter through gauntlet of fans
