EC135P2+ (Study assist)

What type of transmission is installed in the EC135P2+?

It's a two stage flat design gearbox, with anti- resonance rotor isolation system (ARIS).

Explain the Main rotor system on the EC135

It's equipped with a four bladed bearingless main rotor (BMR). The inboard flexbeam enables movement of the blades in all axes. Blade pitch angles is controlled through integrated glass/carbon fibre control cuffs.

The main rotor control linkage system is of what design.

Conventional design.

The hydraulic system for the main rotor controls is designed as a what type of system?

A duplex system with tandem piston (both systems are active).

In the case of a failure of one hydraulic failure is there a redundent system in place?

Yes,
In the case a failure occurs with one of the systems, the remaining one has sufficient power to ensure safe flight operation and a safe landing.

Can the aircraft be operated without any hydraulic systems operational?

No,
Aircraft control can't be maintained without hydraulic assist.

What type of anti torque system is installed on the EC135?

fennestron- type anti torque system.

How many rotor blades are installed in the fennestron rotor system?

10 blades are installed.

How is the tail rotor system controlled from the pedals to the input control lever of the fennestron?

It's controlled via a flexball type cable.

The fuel tank system comprises of what?

Two fuel tanks, a fuel supply system, a refueling and grounding equipment and a monitoring system.

What type of electrical system in the EC135?

A fully redundant electrical 28VDC system supplied by two generators and a battery.
