UAVHE RW1-79 APU

Key Features

Engine Design

Designed for use as a power source for UAVs. Easy to configure and manage. Flexibility of possible installation. Consistent performance over a wide range of altitudes and temperatures.

Air Intake

Ducted air intake and exhaust for cooling system and co-axial air flow of the exhaust system

Fuel System

Low fuel consumption. Operates on heavy fuel, including most common civil and military jet fuel grades such as Jet A, Jet A-1, JP-5, JP-8 and Sustainable Aviation Fuel (SAF).

Electronic Control

Multiple RW1-79 APU units can work in parallel or in hot-swap mode. A power balance controller can integrate batteries, supercapacitors and one or more generators into a common bus.

Cooling System

Forced cooling with pre-filtered air for all heat-emitting components. Ability to operate in any position and with accelerations up to +6G

Electrical Output

• – Output power 11kW, up to 16kW Peak.
• – Output voltage 28VDC (MIL-STD-704).
• – Output voltage options: 48/96/144/192VDC

More details

Engine Design

• · Air-cooled rotary engine with direct drive generator on permanent magnets.
• · Electronic fuel injection with forced electric supercharging..
• · e-Supercharged fuel intake through the rotor with centrifugal acceleration of a pre-atomized fuel-air mixture.

Materials

• · The stator is aluminum, CNC-milled from a forging with a thin sleeve of hardened cast-iron liner.
• · Rotor: Aluminum with DLC coatings in the seal channels.
• · Apex seals: Polished tungsten-carbide apex seals.
• · All external surfaces have hard anodizing and protective coatings to meet MIL-STD-810
• · The laminated stator of the generator.
• · Neodymium magnets in a Halbach array on an aluminum rotor.

Fuel and Ignition System

• · A BLDC electric motor for precise maintenance of selected pressure in the intake tract drives a supercharger impeller.
• · Submersible high-pressure fuel pump and pressure regulator.
• · Electronically controlled piezo injector with ultrasonic control of counter-focus of the spray flame. Sub-5 µm droplet size.
• · Dual ignition with two spark plugs.
• · Complies with MIL-STD-461/464. Insulated wires, connectors and housings with EMI protection.

Cooling System:

Forced air. Air intake through the generator stator for cooling. Air is discharged coaxially around the exhaust port.

Electric output

• · Continuous electrical output: 11 kW
• · Peak electrical output (5 min limit): 16 kW
• The system provides modular DC power through configurable low-voltage channels (48/96/144/192 VDC), allowing flexible distribution and parallel operation of multiple units.

Flexibility

Multiple RW1-79 APU units can operate in parallel or hot-swap mode, seamlessly integrating with batteries, supercapacitors and additional generators through a power balance controller.
