UAV Factory, a Latvian based Unmanned Aerial Vehicle (UAV) manufacturer had a requirement to accurately measure fuel level and usage on-board Penguin B, a small class UAV used as a training platform to Universities, Armed Forces and research establishments.
Fuel monitoring is critical for safe 'return to base' functionality and to provide live telemetry to the command & control base-station.
The positioning of the fuel tank in the Penguin B aircraft presented a tough design challenge as only the rear of the tank was accessible; therefore a customised sensor design was required to fit the irregular shaped fuel tank. Additionally the proposed fuel level sensor must be easily changed-out or retro fitted without major strip down of the aircraft.
Using provided 3-D CAD model data of the tank, Gill's team of design engineers developed a new 'side-entry' sensor mount which was tested and evaluated to ensure application compatibility. To ensure the sensor could be fitted into the rear of the fuel tank, a special 'dog-leg' design was developed.
21 sensors were delivered to the UAV factory for use with the Penguin B UAV aircrafts and the sensors were used to provide valuable measurement data within the company's world endurance flight.
