Hybrid Power Gen-Sets

LaunchPoint Technologies is developing gen sets based on reciprocating engines for hybrid electric UAV power sources.  Reciprocating engines have much higher efficiency that turbine engines.  For mission durations above one to two hours the reduced fuel payload required for an efficient reciprocating engine can make the combined fuel and engine mass lower for a reciprocating gen set than a turbine-based gen set.

We presently have prototypes in-process for 1.5 kW, 6 kW, 12 kW and 40 kW gen set units.

40 kW Gen Set Based on Rotax 582

Our hybrid electric UAV bus controller is integrated with the engine controls and generator controller to provide seamless management of power resources on the bus and maintain engine speed and bus voltage during transient events.  If a generator controller is utilized that features bi-directional active power conversion electronics then the alternator electric machine can also be used as a starter motor for the engine.

To achieve high specific power we utilize the highest performance engines available and couple them with our high specific power electric machines to achieve an efficient, light-weight system.

We have integrated a dual halbach array alternator with a GSE heavy fuel engine (http://gsehfe.com/ ) to create a 6 kW heavy-fuel electric power source that weighs 13 lbs. including the active electronics to enable the alternator to function as a starter motor.  The unit provides 1 kW/kg for conversion of heavy fuel to electricity including the active power electronics enabling starter-alternator operation.

Our 1.5 kW hybrid electric UAV gen set (with an associated LaunchPoint smart battery pack) will be a plug-and-play hybrid power source replacement for small multi-rotor UAVs that will increase endurance up to 1.5 hours from the present 20 minutes pure electric on a large battery pack.
