AHD added a fifth blade together with some major design changes on the tailboom:

Maybe the new fenestron, main rotor and blades of the X4 project ?

The X4 will be the replacement for the Dauphin/EC155 class, for the 135 it is called the X9 project.

I didn't know about the X9 program but the EC135 s/n 001 seems to have been the testbed of a lot of things from Eurocopter so...

After 2 shocks today, have they finally got rid of the collective / metal watch strap phenomenon?

Sweaty hands eh?... Keep your hand on the collective twist grips and you want get zapped. I think is designed to switch the transponder to GND and VEMD flight time recording, although not sure on the later.

Far from it sherpa, I'm not one for holding the collective 'top box'.
Apart from missing the bit of my post that says "collective / metal watch strap", its a bit hard operating the radio selection box, which is when the shock occurs, without taking a hand off the twist grips!

Why you get a shock?

A relay is an electro-mechanical switch that opens and closes under the control of another electric circuit.
When current flows through the coil of the relay, a magetic field is created that causes an armature to move, either
making or breaking an electrical connection. When current is removed from the relay coil, the armature returns to
its rest position. It is important to place a diode across the coil of the relay because a spike of voltage is generated
when the current is removed from the coil due to the collapse of the magnetic field.
The pin in the end of the collective grounds the primary coil of the "Ground Relay 2CX".

As the field within the relay collapses (through your arm) you get a taste of the spike. Ouch!

I have personal experience and it definitely bites.

32-60-03 Ground Relay

PP20E -> CB 1CX GROUND REL -> Relay 2CX -> 8VE COLLECTIVE PIL

It controls various things through TB27 A,T,J and V respectively.

Maybe 2p worth of diode may fix it!

Needles to say that the radios may endure the spike as well?

CVR/FDR Lite

EC135-31-070 DISPLAY AND RECORDING SYSTEMS – Vision 1000 - Retrofit of a Vision 1000 cockpit camera

Description
The Vision 1000 is a cockpit imaging and flight data monitoring device and is installed on the center post.
The system captures critical inertial and GPS positioning data as well as cockpit imagery and ambient noises.
The flight data, imagery and noises are stored on a crash-hardened memory module as well as on a removable SD HC card for use in the management and visualization program.

Benefits for the customer
 Increased operational safety - Can be used to replay the flight scenarios during training
 Recording of positioning data (location, altitude, etc.)
 Recording of cockpit imagery (instrument panel, flight controls, partial exterior view) and ambient noises

Analysis of recorded data with the management and visualization software (included)
 Additional 3D software available at Appareo Systems (not included)

Technical features
Weight: approx. + 0.8 kg
Image resolution: 2 megapixels
Image frame rate: 4 frames per second
Audio frequency range: 50 Hz - 15 kHz
 Removable Flash Memory - SDHC card, storage capacity: 16 GB,
Storage time: 4 hours image/audio/GPS/inertial
 On-Board Flash Memory - storage capacity: 8 GB,
Storage time: 2 hours image/audio/GPS/inertial
Kits -

Vision 1000 camera EUR 7500.00
Retrofit of the reading light EUR 150.00
Name plates CB I, CB II, SW III EUR 750.00
Standard parts EUR 50.00

Labour -

Electric - ~ 30 Hours
Mechanical ~ 25 Hours

Looks to be a fairly effective solution considering the options available.

Thanks RVDT, although I think it has been covered previously in this thread. I was just asking if the new design might have a different grounding system, removing the chance of this little shock.

Mind you sometimes it comes in handy after going round and round and round and round and round and round and round and round and

Airbus Modifies EC135 as Environmental Tech Testbed


A German photographer spotted a modified EC135 at Airbus Helicopters’ development facility in Donauwörth, Germany. Most striking is the light twin’s new horizontal empennage, moved to the top of the vertical fin.

The bottom of the vertical empennage also has a different design and the tailboom now appears to have a circular cross-section. In addition, the helicopter sports five main rotor blades–instead of four on the stock EC135–with swept tips. The landing skids also have been redesigned.

Asked whether the helicopter is the prototype of a new EC135 variant, Airbus Helicopters answered that it is “testing environmentally friendly technologies on a demonstrator aircraft.” While the EC135 is being used as a testbed, Airbus said the technologies should be seen as “transversal,” meaning not specifically intended for any one particular helicopter model.

Meanwhile, the manufacturer is gearing up for the first delivery of the latest EC135 version, the EC135 T3/P3, which was previously delayed to the fourth quarter. Announced at Heli-Expo 2013, the new model offers several improvements over the current EC135 T2i/P2i, yielding a 66-pound mtow increase and improved hot/high performance.

I'm guessing some X4 linked technologies...

Can anyone shed any light on a co-pilot reversible seat for the 135?

I see it listed in the IPC, Chapter 25, as 'against FD' (Flight direction I am guessing) and the picture showing it facing backwards, but I have had no luck finding any other ref to it?

Yes, usually it's a part of HEMS (single-pilot) configuration, or in hoist operation configurations (HHO)...with hoist on left side.

Is it just me, or does that machine appear to have 5 MRBs ?
