HPG H145 Engine Deep Dive

A deep dive on the Safran Arriel 2E engine that powers the Hype Performance Group H145. Really not anything you need to understand to fly the aircraft in the simulation, but if you're gonna be a real (make believe) pilot, you're gonna have to know your systems!

It was explained beautifully and clearly for sure. Thanks for that.

Congratulations. Very nice.

[@vacuator]

Overall, a very good explanation of the Arriel engine operation.

This, by far is the best information for this particular engine is excellent 👌 Very in depth 👌 💯💯💯👍👍👍

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.

I have discord. Also Shipmeck. I'm active in the HPG discord group

You ever get this bird?

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 ?

[@Shipmeck]

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.

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

[@Shipmeck]

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.

[@ronaldgreen5292]

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.

[@Shipmeck]

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.

Turbomeca Ariel engine

[@vacuator]

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.
