You can pressurize that extinguisher real easy. If you notice the end of the hose is an air fitting shape that will chuck directly into a pneumatic line from a large compressor then just push the handle down and the extinguisher will pressurize instantly. Instead of using that little air fitting. Retired FDNY firefighter here this is how we charged the can after every use.

Thank you Bob! You are the man!

I've only ever done compressor washes on Boeing 767s with either P&W JT-9s and GE CF-6s, but a very similar procedure but we had a spray ring that is fitted in the intake so there is a even distribution of water around the engine. 🇦🇺

I love how the whole aircraft is designed to be this simple...fantastic. Its a bigger process on GLEX's etc. Love how they filled the gap between a biz jet and a private prop plane.

Why am I watching this? I'm not a pilot. I'm not an owner of a jet. I have zero chance to own a jet in the future. So why?

I can't remember what the cleaner was called but when I was crewing SH-3s in the Navy we would spool up the engines, T-58s, and spray it into the compressor section. We had a long wand with a ring-shaped spray head so we could do it from the ground.

I wonder if any aircraft mechanics have thoughts about adding a small amount of vinegar to the water. It really helps to break up dried salt, and then obviously flush with pure water it would also break up mineral deposits

Good idea!

Hello I am curious what are the two sensors protruding in front of the engine. Concerning the compressor wash, since (I assume from your "good enough to drink" comment) that the water just tap water and if so, why use a pressurized water cylinder for the compressor wash? I was afraid that the heavy cylinder or jagged handle might hit the airframe chipping the paint, or worse, fall, denting the wing (4:30)! Since only potable water is needed, Why not just use a normal water hose with typical sprayer? That would mitigate this risk of airframe damage. Look how precariously the pressurized water tank is being held (4:34). Clownish in appearance, sorry Bob. How often is this procedure necessary and what is the cost? Does the engine monitor indicate the need, or do you employ a "gut feeling"? How many gallons of fuel is burned during the 5-minute engine run? A lot of questions! I'm an instrument-rated private pilot who rents 172s. One of my colleagues ordered a SF-50 which should be delivered mid-2024.

@al.waterloo

4 ай бұрын

Awesome. Your colleague is going to love it! Where will it be based? Those two sensors are for the FADEC computer. It takes the temperature and pressure readings going into the engine. You do this after a certain time interval flying at or below an altitude in a marine atmosphere. You’ll be surprised it’s like flying for 30 minutes or more at or below 5000 feet or so. The actual numbers are close to that but those aren’t the actual published specific values - close though…

Interesting.

Interesting. I'm not sure that adequately gets everywhere in the engine though. A lot of manifolds in such a thing. I wonder if some built in spray ports would be better or other system for cleaning. What are those little scoops in the intake? they seem a little aerodynamically ugly to me. Also what are the orange hoses at the back?

@al.waterloo

It’s what the engine manufacturer says to do. The probes are temperature and static pressure probes that take direct measurement at the inlet of the engine for the FADEC computer to control the engine.

I sincerely hope you're using distilled water and not tap water. I wonder if flying through rain would have the same effect? No doubt the post-rinse run time requirement of 5 min both dries the engine while recharging the battery.

Ideally pure h2o sure but is there a practical benefit that would make it worth the cost? Is mineral buildup a worry for an open combustion engine? In for ICEs mineral interaction or buildup in the cooling system should be avoided. Water injection systems use distilled/deionized to keep the valves and atomizers clean. But here it seems like unlikely to have a negative impact right?
