Agreed.

AGREED!!! That is just the sweetest purring music!!!!!

The Pratt and Whitney Canada PW207D1 is a sweet sounding engine. Makes me quiver and squeal a bit every time one spools up.

Airwolf is all I think of

Yep just like holding two electric drills to each side of your head

Have you looked 😍 into gyro-planes or some call them gyro copters. A poor man's helicopter.

Is that not real then.?

Backyardmech1 Yep. Pratt Canada PW207

And it does not require the 2-minute cooldown that the old RR250's did in the Jetrangers.

I love it dude turbine Chopper AIRWOLF

Me too bro

Fair analogy.

Exactly, still seems like quite a lot to do/check/monitor still in this day and age considering a lot is now already automated anyway and the technology we have.

Well, the EC135/145, MD900/902 and the A109ˋs with the PWC 206/207 engines actually have full automatic start up and shut down. I’m actually surprised he has to „ roll the throttle“…

What do you think is happening in this video? It’s all FADEC, for a multi-engine helicopter it doesn’t come simpler than this.

The 429 isn’t military it’s civilian

@@jameson1239 yes I know. I was referring to helos in general having one purpose off the line.

How often did you happen into, "Well, that's a constructive notion of 'getting high'"?

wraqi Good advice. However I would not advise on trying to fly any ultralight without training - not if the owner values their life.

In modern turboshaft engines, the turbine driving the rotor is not mechanically coupled to the gas generator (made of compressors, the combustion chamber and turbines driving the compressor). Reason why they are also name « free turbine engines ». Thus, disengaging the rotor would offer no benefit as the power turbine (« free turbine ») is not driven by the starter. On some helicopters, the rotor brake can be activated at start, but it is for high wind capabilities reasons. The situation with old engines with their gas generator linked to the rotor was different. A clutch was preventing to drive the rotor at start, thus avoiding design issues with the starter. But the clutch itself was meaning weight and reliability issues.

On turbine helicopters it doesn’t matter if the rotors are turning when the engines are at idle. The starters don’t even turn the rotors.

LOL

Yes

We didn't have ground handling wheels at the time.

That would be a huge waste to shorten a very significant (& expensive) maintenance schedule just to move from one space to another on the same paddock. Poor planning.

Ok...tell me which one you would _rather_ do, when given the opportunity 😂

Steeyuv I enjoy it quite a lot so I’m rarely bored

If you're bored flying a helicopter, your'e doing it wrong.

Haha. I could almost have posted that flight as a "Vine". Lol.

its a fadec assisted start actually. less stress on the pilot

I believe there is a version with more displays, for training.

Sure..there could be a FLIR/ TV CAM screen in it...and more radios... :)

DML Channel the one I work around has duplicate cockpit panels and controls for the pilot and copilot

Too much fuel entering the combustion chamber and/or insufficient turbine RPM. Much worse damage for a turbine engine than piston.

The turbines of the hot sections of the engine are designed for a maximum temperature. Increasing the power of the engine without adding weight is made by in increasing this max sustainable temperature. But there is still a limit : an overtemperature at start (typically caused by a malfunction of a governor element or air permeability of the fuel lines) can damage the turbines, and the cost of repairs quickly amount to hundreds of thousands... On recent helicopters equipped with Full Authority Digital Engine Controls (FADEC) the start sequence will be stopped automatically should the temperature threshold be overshooted. On older helicopters, it is relying on the pilot survey at start, and the overtemp sequence is really quick ! This overtemp is sometimes called « hot start ». But on turboshaft engines the « hot start » wording mostly refer to a normal procedure at start. If the residual internal temperature of the engine remains high before starting (further to a previous flight combined to a high OAT or an aborted start), there are specific procedures to start the engines by first running the gas generator with the starter without injecting fuel.

@@noosphere6132 oh ok i see ... So what about engines with afterburners? Or military jet engines? Does the same rules apply or do they changes because it has an afterburner? Im just wondering sorry for the questions im just trying to understand all of this

I would like some pointers on building a car turbo jet engine so i need to know as much as i can . i like to build things

The design of a turboshaft / turboprop engine is nearly the same than a single flow jet engine. Instead of collecting the energy of the hot gases with a power turbine driving the rotor or propeller, you collect this energy on the exhaust casing. The afterburner consisting in providing additional energy through burning fuel after the turbines : high energy because you are not limited by the max temperature endurance of the turbines but with low efficiency (compared to the combustion in the combustion chamber which provides a very efficient air / fuel mixing) thus impacting the aircraft range.

Well, the AH-64 is pretty fast as helicopters go, and can sneak up on adversaries, although differently from the fictional gunship.

Obviously very experienced and can do it easily, although checklists should be used but the vid is startup only.

Pnp crash sir ano,?

one word: Subtitles

So you're saying it's too slow and others are saying it's too fast, can't be both?
