Overview for Raccoon

General Overview:

The Raccoon cargo drone is a mix of a tri-copter (but with five lift rotors), and a fixed wing aircraft. It contains some of the following features:

Landing Gear – The drone forgoes conventional landing gear in favor of a landing peg on the tail and two dorsal fins that provide a tripod style landing.

Waterproofness – The drone consists of carbon fiber and EPO foam exterior with compression seals between connections to provide a high level of water resilience. Electrical connections are also taped over.

Modularity/Ship-ability – The drone is assembled on-site from 15 main sub-assemblies. Each component is less than 2m in length. Large assemblies, such as the wing frame, fold in half for transport. The fuselage consists of an upper and lower half, the lower half of which can be swapped out with mission specific designs (i.e. Sensor payload).

Ease of handling – Many of the sub-assemblies are ‘pre-wired’ and ‘pre-assembled’ to reduce on-site assembly, and also reduce errors. The number of screws/bolts was kept to an absolute minimum. Many of the connections rely on components sliding together, and then locked in place with a rod. Additionally, failure prone components (servos) can be swapped out separately from major sub-assemblies.

Weight – At 23.5 kg (including 3 kg cargo), the drone has 1.5 kg of margin.

Safety Provisions – The Raccoon drone contains the following unique safety features in addition to the Ignition Kit parachute and launcher:

-Two separate li-ion battery buses provide primary and backup power

-A backup avionics battery to maintain controlled flight in the event of a complete battery failure

-A ‘Clear Prop’ notification to ground crew before take-off

-Hard switch to disable the lift rotors when the payload bay is being accessed

-Weight on Wheels switch to disable rotors after landing

-Language agnostic warning and hazard placards near the rotors/propellers

The attached systems document contains details on everything listed above, as well as center of gravity, performance, assembly details, and a line-by-line list of requirements verification (trace matrix).
