Israeli unmanned aerial vehicle (UAV) manufacturer Aeronautics announced on 29 May 2024 that it has launched a new variant of its Octoper tactical multi-rotor UAV that uses a hybrid propulsion system to extend its endurance.

Called the Hybrid Octoper, the UAV’s hybrid propulsion incorporates a generator as the main energy source, providing significant mission endurance enhancement. It also features a back-up battery for 10 minutes of stealthly flight, with an in-flight engine on/off capability and 4,000 W of continuous power. The system has a mission endurance of up to four hours.

“Surpassing conventional limitations of electric UAVs, the Hybrid Octoper enables significantly longer flight durations, reducing the need for frequent battery and UAV replacements while maintaining critical persistent surveillance during complex missions,” Aeronautics stated in a press release. “By integrating fuel combustion and electric sources of power, the Hybrid Octoper extends operational capabilities through optimised energy usage and cost-effectiveness.

The Hybrid Octoper has a military-oriented design, with Aeronautics stating that it has “high survivability” and “seamless integration with diverse sensors and other payloads”. The system features an autonomous landing capability, GNSS-denied navigation, and encrypted communications. Its “advanced video processing and analytics enhance situational awareness, while the various payload options ensure mission versatility”, according to Aeronautics.

According to the Aeronautics website, the Octoper has a maximum take-off weight of 25 kg and a maximum payload capacity of up to 10 kg, although this is presumably slightly less when the UAV is carrying its hybrid power kit.

“As part of our strategy to provide cutting-edge solutions for the tactical domain, the Hybrid Octoper marks a significant leap in the heavy multi-rotor UAV product space,” Dan Slasky, president and CEO of Aeronautics, was quoted as saying in a company press release. “With its extended hovering capability, enhanced situational awareness and seamless integration of diverse payloads, it enables maximum mission versatility and flexibility.”

Aeronautics’ Hybrid Octoper multi-rotor UAV has a mission endurance of up to four hours.
