XuHuai X100 – miniature jet engine

Give your next RC jet the characteristic sound and performance of turbine propulsion. The XuHuai X100 offers maximum thrust of 100 N with a body diameter of just 90 mm and a length of 213 mm. This engine from the XuHuai XH range combines an integrated digital control unit, AC motor starting and a matching fuel pump in a propulsion system designed for experienced turbine model flyers. The engine net weight is 1020 g.

At the heart of the engine is a single-stage centrifugal compressor and a single-stage turbine. The rotor is supported by two ceramic bearings lubricated by oil mixed into the fuel. The ceramic igniter ignites liquid fuel directly. The AC motor starter is mounted at the front and spins the rotor via a clutch that disengages once the engine reaches self-sustaining speed. The fitted FOD protective grille helps prevent foreign objects from being sucked in.

The integrated FADEC electronic control unit manages starting, engine operation and the cooldown cycle after shutdown. Fuel is supplied by an external, electronically controlled gear pump with an AC motor, matched to this turbine type. The handheld GSU (Ground Support Unit) allows you to set and display the RPM, temperature and operating data. It can be disconnected before flight, provided the approved connection procedure is followed; engine control remains on board.

Key features

• Maximum thrust 100 N; idle thrust 5 N.
• Integrated FADEC control unit (ECU) with automatic starting and post-shutdown cooldown sequences.
• AC motor starter, ceramic igniter and two ceramic rotor bearings.
• Matching AC motor gear fuel pump and handheld GSU included.
• FOD air intake protective grille included.
• Runs on Jet A-1 aviation fuel, kerosene or diesel fuel with the specified lubricating oil.

• Recommended service interval: 25 operating hours

Performance figures apply at standard atmospheric pressure and an ambient temperature of 15 °C. The engine net weight is not the weight of the complete installed system. Fuel consumption is stated by mass in g/min; it must not be confused with ml/min. No operating point is specified for the approximate X100 fuel consumption, so this is not a guaranteed value at full throttle.

Fuel and lubrication

Jet A-1 or kerosene is the preferred fuel. Diesel fuel is also permitted, but starting and acceleration may be slower and smoke may be more pronounced when using it. Use Mobil Jet Oil II at 5% of the fuel quantity, measured by volume. The bearings rely on this lubricant for lubrication; never run the engine on fuel without oil.

Package contents

XuHuai X100 engine with FOD protective grille, matching AC motor fuel pump, handheld GSU, main wiring harness, fuel pump wiring harness, Festo fuel filter, fuel tubing, ball valve and operating instructions.

You will need the following to get started

• A suitable turbine-powered aircraft model or a safe test stand, appropriate mounting and any required intake or exhaust pipe components.
• A suitable fuel tank, equipment for venting and filling, approved fuel and oil, and—depending on the installation requirements—a fuel air-trap tank.
• The specified engine battery and a separate receiver battery, compatible charging equipment, and an RC system with a latched engine shutdown control and adjustable fail-safe function.
• A CO₂ fire extinguisher with a minimum charge of 2 kg, eye and hearing protection. Also, suitable equipment for handling fuel.

Before the maiden flight

1. Complete the installation according to the full instructions and the model’s guidelines; clarify any uncertainties regarding connections or exhaust pipe dimensions before starting.
2. Check the fuel system and independent power supplies, then set up throttle calibration, engine shutdown and the fail-safe function for the equipment used.
3. Before flying, commission the engine under supervision and carry out a ground test with the model securely restrained, including engine shutdown and cooldown.

Important: Intended for unmanned RC models operated by sufficiently experienced users. Automatic control does not replace supervision. In the event of a fault, do not rely on automatic overtemperature shutdown or on restarting the engine in flight.
