Hans S Posted May 3, 2009 Share Posted May 3, 2009 I have been playing around with an idea. The thought was to use the air pressure built in front of the windshield and tunnnel it to the engine. This would essentually remove the drag created by the normal scoop method. I realize that makes a long way for the air to have travel in an enclosed tube to get to the engine. And it would also create a more cramped area by your feet. Any thoughts? Quote Link to comment Share on other sites More sharing options...
Spodman Posted May 5, 2009 Share Posted May 5, 2009 What a strange idea. Why not use the air pressure built up under the fuselage by the positive incidence?

emteeoh Posted May 5, 2009 Share Posted May 5, 2009 I would have thought that any "air pressure built up under the fuselage" would be a good thing, as it is lift, while air pressure in front of the canopy is parasitic, so using it, if you can, seems like a good idea.

Yes, remember that with aircraft design, you wouldn't want anything strange.... Quote Link to comment Share on other sites More sharing options...

Spodman Posted May 7, 2009 Share Posted May 7, 2009 OK, if we are talking strange I was looking at a trashed Benelli motorcycle while waiting for bits for mine at the wreckers yesterday. Very elaborate plastic ducting takes the air from the front of the fairing (high pressure obviously) to the ducktail where the radiator is. There were more ducts from there to the intake box (which didn't make a lot of sense to me). If you want to celebrate strangeness in a strange looking design then go for it. Can't help thinking it will be difficult to incorporate the neccessary ducting in the existing fus, and getting it through the firewall, and avoiding only being able to see some sort of scoop when you look forward to land the thing. Maybe you could grace us with a diagram of what it is you have in mind?

TMann Posted May 7, 2009 Share Posted May 7, 2009 The theory of cowl-induction is more of a 'auto' related solution vs. an aviation related solution. In aviation there are several areas to choose from that offer better results and result in less drag. For an auto solution, there are other considerations that restrict the areas that are viable (road debris, water, etc.) and drag is not as big of a concern. ........ at least that's my take on the subject.
