You might have to get your own RU-vid channel for the maintenance side of Corporate Pilot Life. A spin-off (you might say). You did a really good job on this video.
Thank you Adam! Great job on the video and that APU must be almost like what a pace maker is to a heart. I couldnt help but think of how hot it must have been working in that hell hole! Been a few years since I visited Florida, but it was this time of year when I was there and the heat and humidity there was worse than anything I experienced when I lived at Ft. Hood / Killeen TX many decades ago. At 630 am it was awful, I hope you were not on there for long! Now you've got some fans of your own Adam! Thank you!
That was great of Adam to help out. The APU is one of those things you flip a couple of switches and it starts and provides power. You never think of it having to be replaced. Thank goodness for A&P's.
Thank you Adam! I really appreciate your time and that of your team. Thank you too Shawn. Have a great rest of your week and as always be safe! God bless. Chip
That APU is absolutely tiny compared to an APU on a C-141 or C-5. lol Military APU: Air Pressure Unit, for pressurizing the aircraft and Aux power. Gulfstream APU: Auxiliary Power Unit, same purpose different name. Thanks for sharing. Very interesting, to be sure.
My dad used to be FE on 141's and flew on 135's before that. Always joked how it was a luxury to fly the 141's since they were told to never use the APU on the 135's due to high fire hazard.
How is that kept cool inside the aircraft while it's running on the ground? I have to imagine that sucker gets hot especially enclosed inside the jet itself.
Just out of curiosity, do you need to have the APU installed to actually have the plane flyable or are you able to per say, be able to fly the plane without it and just start the plane with like a GPU and run it that way? This is pretty sick with how small that APU is yet it produces enough bleed air to start the mains and give power to the plane without a GPU
Hi Shaun, Couple questions... Why did the APU have to come out, was a spare popped in so a/c could go back in service, was there other work to be done on at the a/c? How often does the APU have to be removed - hours or cycles? Thanks to you and the ground team for this.
Thank you Adam so much for filming that for us! Fascinating to see a major component of the plane get pulled, and would even watch you find what's wrong with it. Although palletized like it is, means a rebuilt unit could be put into place.
Wow, this brings back a lot of memories from my design years! This APU looks very similar to the Honeywell unit I did prototype work on from the G5. If I'm not mistaken, the engine spins at around 45,000 rpm!
Me thinks you’ve found your new tech advisor. Well done. He also made it sound much easier than it is. I’ve done it a few times and although it’s not too hard, it’s not all that easy. This is the nice part of being retired, I can sit back and watch others do the work. Still miss flying though!!!
Thanks for taking the time to post and a big thanks to Adam for taking his time to do that for you and the company for letting you guys do that, very cool!
Does the APU on the G-IV actually assist in engine start by diverting bleed air or is it for back-up/auxiliary power only and the engines start themselves? I used to start military jets many, many moons ago on the flight line with our version of a "jet engine in a box", but it occurred to me the engines on this style jet probably don't need bleed air to start???
Right now we are ripping apart an Allison 250-c20 kind of makes me wonder if it could be used for an apu instead of a helicopter engine they look to be pretty similar size
THANK YOU ADAM. Very cool, and amazing how ease of servicing is building into design. A highly technical, rollerscate with wings. But, the most intricate machine that makes it all work has two eyes, two ears and a cerebellum. Take that AI.
Thank you Shaun and Adam, well Adam mostly but to the whole team there who seem to be supporting you and your channel :). That APU didn't look that large. Somehow I strongly suspect its cost is even larger.... Question Shaun. Can an aircraft still fly with an inoperative and or removed APU?? I would guess yes but with restrictions. Take care everyone and keep safe out there, look forward to the next wonderful tech vid :)
Hey, Shaun, another cool video as usual. Question: What's the fuel consumption on the APU? Obviously it's not sucking Jet A like the Rolls Royce engines themselves but I was just curious. Thanks!
Next time he changes out the TROV or relief valve, have him film that. We build and repair them in TUS, and have been told by Gulfstream that the primary cabin pressure valve (TROV) is a royal pain to install and remove. We get them with the actuator beat to hell from the installation process.
Saw the title and planned to hit like even before seeing the vid. Then you came on and said you weren't there...oh oh! What a great guy for Adam to step up to the plate, videoing it ! I wish I could've hit double like! Add me to the list of people who are curious as to why the APU had to be pulled, and what the next step was going to be.🤔
Great vlog Shawn, and thanks to Adam for the great video!!! I deal with APU’s on a commercial airliner scale, but they are pretty much all the same. So it was nice to see it on the corporate side!!!
