I think they flew a 5-blade head on a "Quiet" EC135 a while back also.
Maybe they are doing a rotor upgrade along the same lines as the 500C-to-500D upgrade and hoping for the associated improved performance the extra blade can bring.
Will a NOTAR upgrade follow later?

Comes 11 years after the five-bladed Advanced Technology Rotor was first tested on an EC145:

@Lucing - not operating in a tropical country, still, the first twin helicopter I fly designed with power to spare.
In situations, where the BK117B2/C1 needed take off power or wasnˋt even capable of hovering out of ground effect the H145 T2 mostly operates below the blue line, which means within OEI 30 sec range.
cruise 2x74%, OEI 150% 30 sec, 143% 2 min!!!!
The only drawbacks - comfort, itīs vibrating and you have to be vigilant to reduce from T/O Power to cruise passing Vy cause the bird is accelerating quickly - and past Vy +20 you ˋ re back to 2x74 MCP limit from 2x95% T/O Power (104,5 transient)

Thanks Bull for the info
So over all its a fine bird to be operated in corporate / vip transport??... and one more thing how fast can you go in cruising speed with all the loads that i mentioned?thank
With LAVCS on PAX setting - still more vibrations.
You get used to it - but feel the difference, when jumping in occasionaly on to one of the old birds ;-)

Really lots of gadgets, which make pilot life easy. With the rigid rotor head much space above the heads for people going to/from the bird.
Speed - I usually fly with external add ons (camera, High Intensity search light) and cruise then is about 125 KIAS
Without close to 130 KIAS, it isnīt as fast as the EC155.

In my opinion and after about 400h in it I would not recommend the H145 for VIP. The LAVCS, which was supposed to be an optional equipment, didnt become standard equipment because Airbus is being generous!
The LAVCS is making the vibration bearable, but its still quite a bad vibration level. Anyone who has flown the H155 will think its broken and anyone coming from an H135 will think someone messed up the tracking really bad.
The other thing is, that the vibration are also creating a deep drone that is very annoying on long flights without active noise cancellation (which we dont use / have in our helmets).
The LAVCS motors have actually ripped themselves out of their mounts in the past, which tells a story on its own.
We end up in an aircraft that has electric motors countervibrating a bad vibration from the main rotor and helmets counterscreaming at us to compensate for drone from the structure...nothing gets to the root of the problem, which would be a redesigned (five-blade) rotor and also a dampened (ARIS?) mount of the MGB to the cell. The Five-Blade-Rotor might do the the trick alone (and it actually does according to some Airbus insiders), but the old BK117 way to attach the MGB is no smart solution either IMO.

Hello to all
One quick question is there a different RFM to the EC145 and one for the H145? Or they have the same RFM only with some extra supplements for the differences between the model.
Thanks

Does Total have any EC145C2 (BK117C2) globally on contract
Long shot for the RW community.
Does anyone know if Total has on contract, anywhere in the world, the EC145C2?
