Unreal. Thank you for such an amazingly presented video. I'm about to get the H145 and the Action Pack and dive into MSFS. Pretty sure there are loads of people who would love to have you in a Discord for MSFS. Do you have one, or are you part of one? Subbed.
Yes. Very subtle. It's mainly the mounting of the two engines. The 2D is is a single forward mount to be used in a single engine configuration vs the 2E having a dual forward mount. There are some very minor accessory differences as well but when I went to the Safran Level 2 school for 2E, I actually disassembled/reassembled a 2D instead of a 2E because they are so similar.
Hi @Shipmeck. Great video. Seems there is no clutch on H145 between engines and rotors. Does it mean that when the second engine is started, the power turbine is already spinning ?
There is a sprag clutch in the transmission, that disengages when the transmission spins faster than the input shaft. When the 2nd engine is started and the power turbine reaches the speed of the transmission, the sprag clutch starts to engage and providing torque.
@@Shipmeck cristal clear, thanks. You may answer another question: what is the circular tube in the middle of the tail. If I'm not wrong, it's an antenna but I failed to find a clear explanation. It looks more like a pipe (for hydrolic pump) or something.
All values are given at 100% maximum rated. 100% n1 will rarely be seen. Nr varies between 103.5% and 96.5% depending on airspeed and density altitude.
So I'm not familiar with the c-18, but it seems almost identical to the R3? Such an interesting design with the centrifugal ducted reverse flow. Elegantly simple.

It was explained beautifully and clearly for sure. Thanks for that.
This, by far is the best information for this particular engine is excellent 👌 Very in depth 👌 💯💯💯👍👍👍
Overall, a very good explanation of the Arriel engine operation.

Subbed.
I have discord. Also Shipmeck. I'm active in the HPG discord group
You ever get this bird?
What an amazing video! do you know the Differences between the 2E and the 2D engines that are on the H125 and H130?
Yes. Very subtle. It's mainly the mounting of the two engines. The 2D is is a single forward mount to be used in a single engine configuration vs the 2E having a dual forward mount.

Thanks! It’s a great engine. I really enjoy flying it on the h125 and H130. Easy to use and forgiving.
Congratulations. Very nice.

@yamatubeable are ypu talking about the u-shaped pipesbl, parallel to the ground opposite each other? ILS antennas.
I'm assuming that the rpms, stated on this chart, is, @ full-throttle, or 90%? Right? At idle, the rpms for N1 and N2 are much lower.

Now!! Do another video on my favorite turbine engine: The Rolls-Royce- Allison C-18, 20B series!!🤨🤨

Turbomeca Ariel engine
Safran has replaced Turbomeca as the new name of the manufacturer of the Arriel series of engines.
*in my best Spaceballs Yogurt voice* MOICHENDISING!!!!
This company is actually named Safran Helicopter Engines. And all the drawings here have been stolen from SHE Academy.
