Cowling Installation Tips

- Опубликовано: 21 авг 2024
- Experimental aircraft kits do not supply their engine cowls ready to install. Plenty of tricky trimming and fitting is required by the builder. Little instructional guidance is included with the documentation so the builder is left to his own devices to figure it all out. This short video provides guidance by an expert builder (Mark Phillips) on how to approach and execute a good fit with your airframe. Mark demonstrates a cowl fitting on a Rans S-19 homebuilt kit with a Jabiru 3300 engine.

Nice job! Something tells me this isn't he first time Mark has gone through this exercise.
Nice AZ snowbird bird there!
See you at sun-n-fun
Thanks for another great video. Where is Mark Phillips located?
Just curious. Is that place in AZ called CH? I will leave it there. :)
That’s a good looking cowl! I may have missed it, what plane is that?
Rans S-19
Looks to me like you're in Arizona-- maybe in or near Buckeye. Am I right?

Might be a silly question but why on most kitplanes is the cowl such a custom thing? Seems like endless trimming for something that for a given engine should be standard dimensions. Is there really that much variation between engines and aircraft?
Yes, there are. Plus cowl manufacturers would rather make one version rather than 10!
@@HomebuiltHELP Thanks. I guess what I meant is for a given standard cowling that fits a standard engine (let's say as exactly specified in the manual no mods) why is there so much trimming and tweaking to get it to fit? For example on pre-punched aluminum like the parts in the kit itself, you don't have to do endless trimming to get parts to fit. Is that just because fiberglass is less precise and sags, etc making each piece a custom piece of artwork for that specific plane?
@@unclefreddy2009 Aircraft kit manufacturers typically don't make or sell engines. You decide on an engine (almost a dozen popular choices). You decide on a propellor. You also need to get an engine mount that fits your choice of engine and aircraft. Exhaust systems and oil coolers further modify the cowl. The permutations of possibilities are endless. The cowl manufacturer is only going to make one generic model. Many times you cannot find a cowl that fits and you have to make your own or highly modify one that is close. There are a few kit models that specify every single component, including engine and prop - they can produce a ready-to-go cowl. But that is a big exception.
Nice spinner. #CumminsSpinners
