High Eye - HEF 30 Unmanned Helicopter

New product

The HEF 30 is an unmanned helicopter with a two-blade single rotor. Because of its size, weight and capabilities, it creates a class on its own and brings industrial reliability into the lightweight UAV market for the very first time.

More info

Its strength lies in the fact that it weighs less than 25 kg and it will fit in any small van or estate car without any prior disassembly, whilst still being able to easily outperform all electric competitors. It offers flight times up to 3,5 hours even when carrying modest payloads. It never needs a recharge, which means that except for some short refuelling stops, the mission can always continue. The system operates fully automatic and through nearly all weather conditions. Manned helicopter aviation finally found its first true competitor.

Technical
he HEF 30 design was created in 3D and 2D CAD and is under control of an extensive Part Data Management System. 
The frame of the helicopter follows a modular layout and is constructed from a mix of carbon fibre and aluminium alloy, whilst the monocoque fuselage, tail boom and landing gear have been made solely out of carbon fibre. All aluminium parts, including the rotor head, tail rotor and transmission, have been surface treated to reduce corrosion whilst operating in maritime environments.

The propulsion is provided by a 32cc two-stroke petrol engine, which drives the rotors via a maintenance-free, industrial quality, belt-driven transmission. Fuel is supplied via three integral tanks and a simple gravity-feed system. A brushless alternator provides continuous electrical power to all on-board systems, including the payload. A back-up battery provides power in emergency situations and when the UAV is on the ground, with the engine switched off.

A mil-spec external connector allows an operator to provide external power, without having to open the system. The entire electrical system is EMC-shielded and thoroughly protected against water ingestion. The main rotor, tail rotor and throttle are operated by industrial Volz servo actuators. All flight control linkages utilize maintenance-free IGUS connections. Many ballraced-bearings have been designed out of the system or have been replaced by long-lasting friction bearings.

Technical
A clever combination of well-proven combustion technology, modern lightweight materials and aerodynamic design, give the HEF 30 the kind of performance that one would expect from a product which complies to these quality standards. High Eye designed the HEF 30 for a maximum take-off weight of 21 kg. At these weights, it can safely lift 5 kg payloads, without affecting the rest of the performance and manoeuvrability.

Naturally, the flight endurance of a helicopter depends on the type of mission. Moving forward at pre-defined speeds can vastly reduce fuel consumptions and increase the endurance even further. When flying at the speed for maximum endurance, the HEF 30 will fly beyond 3,5 hours with a payload of 2 kg, without refuelling. In hover, it will easily fly 3 hours, whilst only using 5 litres of petrol. Of course, the HEF 30 can also fly faster. It is currently limited at 70 knots, which equals 130 km/h. Because of a safe excess of power, it can fly comparatively high and altitudes in excess of 6000 feet offer no problem for the system.
