CFM LEAP 1A break down … this is a long video but lots of information there. I apologize I couldn’t get the other side of the engine open, but I hope the images will get the point across.
Thank you all for being here and watch and supporting.. I’ll keep doing what I do and I want you to keep learning. Cheers 🤙 till next time.

@NovejSpeed3 11 месяцев назад

Can you please explain why the LEAPs on thr MAX need so long to start while the NEOs don't. I understand about the bowed shafts and thermal expansion I just don't understand why one has the problem and the other doesn't. Great video!!! Loved the test run at the end!!!

@StigAviation 11 месяцев назад

Good question! and you kind of answered it yourself, the shaft bowing is the reason, the LEAP 1B has a bit of different configuration when it comes to the Compressor staging. Both engine do take a while ( especially on the first start of the day)

@pmbuthia4210 11 месяцев назад

Thanks for another informative video. Nice to see the highly praised CMF Lp1. I have a kinda stupid question. When a pilot decides to dump fuel. Is it via the wings or the engine have a release valve?😅😅😅😅

@StigAviation 11 месяцев назад

Good question! It depends on the aircraft, some aircraft dont have the capability do Jettison fuel ( A321 cant) But for example the 777 can dump fuel , it will be selected from the flight deck on how much to dump and the fuel will drain from the wing tips jettison tubes.

Could you show where the pressurized air exits after driving the starter? Is it vented into the bypass stream, or is there any exhaust similar to the one for the engine anti-ice?

@StigAviation 11 месяцев назад

Yes indeed they do. Blade expansion is a normal thing within Certain limits... if Blade begin to expand too much that's called Blade Creeping ... at that point it will start to cause damage to the abradable liner...blade would need to be replaced.

@StigAviation 3 месяца назад

Well the leap 1A/1B is a very different design. It has advanced technology much like the GEnx. FMU and HMU work much the same in concept but how it does its job is different. Different compressor staging and well as advanced materials in leap engines.
