Avartek Boxer Hybrid is a gasoline powered unmanned aerial system (UAS, UAV, RPAS or simply a drone). The main feature of Avartek Boxer is the hybrid system that provides all the flight energy by transforming gasoline into electric thru its onboard power generator for much longer flight times while maintaining the heavy payloads of large LiPo powered drones.
Instead of carrying heavy batteries the Avartek Boxer Hybrid is designed around a liquid cooled mini generator power plant that transforms gasoline into electrical power. Currently the Boxer generator is capable of delivering 4 kW of energy which translates to 5 kg of real payload and 2 hour flight times. This quadruples the flight mission lengths and provides easy on field operations due to the lack of battery management and charging problems.
The Boxer design is fully custom. The airframe was designed by Avartek in Solidworks and all parts are manufactured in Finland. Only motors, escs, the flight controller and other electronics are out sourced.
The whole copter is designed around the hybrid generator’s capabilities of producing 10x more energy than similar weight in LiPo batteries. 4 kg of gasoline provides 2 hours of flight time at take-off weight of 25kg, while a typical LiPo battery in this size of a drone of 11kg would only provide 30 minutes. 4 kg of gasoline (5 litres) equals 40 kg of LiPo batteries. On field operations greatly benefit from the very quick duty cycle of hybrid drone by offering easy refills instead of on battery management and recharging arrangements.
Boxer uses open source Arducopter code in a Hex Orange Cube flight controller and dual GPS/Compass setup for enhanced redundancy and accuracy. Boxer flight controller is mounted on a Kore board for better and lighter cabling. The flight controller system provides high performance, easy mission programming with rally points, fences and excellent fail safe programming and an easy to use system with unparalleled options for customization both from flight controller, sensor and add on hardware as well from the software perspective. Hex Cube Orange with Arducopter firmware is 100% open system and compliant with latest technologies.
Avartek offers ready made payload setups. Safe, quick mounting and fully suspensed – ready to mount the sensor, IMU and auxilaries, such as onboard PC and telemetry/cloud datalinks. In Boxer typically auxilaries are mounted inside the airframe while the IMU is securely attached to the sensor.
Quicklocks provide quick mounting points to the hardware rail underneat the airframe. This provides quick access to the payload and allows for quick payload swaps in the field. The long payload rails and heavy lift capability makes the Boxer an ultimate multi sensor UAV. Boxer features a large deck that can accommodate payload auxiliary sensors such as hyper spectral camera irradiance sensors. Payload GPS antenna can be attached to the antenna tower. Cabling can be pulled thru the body with customisable deck covers.
Payload Power System
Onboard payload power system provides 12V/8A power for the mounted payload. Payload power is reachable by an XT90 connector.
Avartek designed Brushless Power
Avartek Boxer motors provides excellent flight power for the Boxer Hybrid drone. These brushless motors features industry’s best bearings for minimized vibration and durability.. Boxer brushless motors are regulated by T-Motor 60A speed controllers for best multicopter performance.
Boxer Hybrid uses the 4 KW Pegasus Range Extender. This generator is now well tested and the generator firmware has reached a mature state where users can expect reliable performance with well designed failsafes. The generator system is very light weight and provides industry’s best weight/power performance.
Avartek designed muffler provides excellent engine noise muffling with zero power loss. Muffler works great thru-out generators rpm range. Avartek Boxer muffler makes the drone so much less noisy. We will post exact noise test result once available. Test will be held in Finland, September 2020 by Finnish Traffic Management and VTT Research (governmental technical research institute).
Festo fueling valve is easy and reliable.
