Overview for CargCruiser

Design Details
  • The CargCruiser was developed with maximum payload capacity and safety in mind. Inspiration was derived from the C-17 body style. This 25 kg concept is fully modular with all disassembled components under the 2m requirement. Future expansion has been accounted for in the design, should regulatory weight limits be increased the CargCruiser will be able to maximize the benefits to the full potential. The design is fully water proof including the actuators and outer quad lifting motors. 
Fail Safe Components Battery 
  • 3 packs @ 837 Wh each 
  • 1 pack required for 60 km trip
  • 1 + half pack required for 100 km
  • Available 3rd battery held in reserve currently for future expansion + longer range 
  • Return-to-Base Empty Alternative Configuration; allows for 2 batteries + half pack for ~200km range
  • Weight evenly distributed over CG
  • Large battery surface area minimizes moderate thermal runaway risk with high energy density NMC battery
  • Recommended to be used in conjunction with on board Battery Management System for added margin of operational safety to monitor battery SOH in flight, which in the event an anomaly is detected with battery(1) it can automatically transfer AV power to battery(2) avoiding probable flight termination via parachute or other damage to the payload/AV
Battery Bay
  • Swappable battery bay dependent on operating environment 
  • Lightweight Aluminum Variant for hot OAT configuration
  • Insulated Variant for cold weather 
  • Heat sink design assists in maintaining nominal battery temperature
  • Added safety measure to prevent a thermal runaway event 
  • Available 3rd bay for future expansion + extended range empty 
Ground Proximity Safety Measures
  • Before ground operators interact with the AV they will engage a safe switch killing all power from the batteries and preventing the motors from being activated autonomously. This will be located on the nose of the aircraft well clear of the propellers. The risk to possible nearby pedestrians post landing will be mitigated by installing a squat switch, that when engaged will not let the motors receive power until a reset button or “Ready for Takeoff” switch is pushed on the aircraft nose by the ground operator. 
  • For autonomous drop-and-go operations the safety mechanisms described above will be deactivated requiring the landing sites to be cleared (possibly visually by air operator via the on-board camera). Future design plans will include an autonomous delivery option, however as of the date of this build the AV will require a ground operator for payload extraction. 
Payload Bay
  • Dimensions 547x417x201mm (1.45 x required volume)
  • Rubber weather stripping seals bay to fuselage
  • Honey comb payload stabilization is designed to encapsulate payload using a bungee web tethered to a central expanding fabric mesh
  •  Mesh increases payload survivability in the event of inadvertent flight termination
  • Light weight constraint system, high volume payload availability
  • Horizontally sliding for payload extraction from beneath fuselage   
  • Payload is secured to airframe by two latches with safety
  •  Main payload bay is interchangeable with any mission driven attachment for lock-and-go usability
Landing Gear Concept
  • All Terrain Gear
  • Low drag fairing design 
  • High surface area on landing pads for all terrain types
  • Connects to internal CFRP frame for robust structure
  • Can be outfitted with rubber flex pads to dampen hard landings
