hysot Posted January 27, 2014 Posted January 27, 2014 That seems to be the popular misconception. Here is a better explanation: http://www.allstar.f.../airflylvl3.htm Awesome, I've been looking for a such online explanation for a while! Thanks Quote
Jim Posted January 27, 2014 Posted January 27, 2014 That seems to be the popular misconception. Here is a better explanation: http://www.allstar.f.../airflylvl3.htm True! Otherwise it would not explain a plane being able to fly upside down Quote
Blakbird Posted January 27, 2014 Posted January 27, 2014 'lift' is created by making air flow faster over the top surface of an object compared to the flow of the air underneath it ... this creates lower pressure on the top surface and so 'lift' That seems to be the popular misconception. Here is a better explanation: http://www.allstar.f.../airflylvl3.htm Seasider's explanation was correct, not a misconception. You may have noticed he mentioned that he has an Aeronautics degree. Seasider has summarized Bernoulli's Principle which, when applied to an asymmetric airfoil, explains how you can generate lift even with zero angle of attack. However, it is also true that any flat plate can also create lift simply by inclining it to the airstream. For example, you can stick your hand out a car window and experience lift by rotating the angle. In practice, real aircraft use both effects. Having a positive angle of attack generates a lot of drag, so it is not a very efficient way to create lift, especially when moving at high velocities. Modern jet aircraft have complex airfoils that generate significant lift with minimal angle of attack. The quoted article is interesting and does a good job of expounding on the more esoteric details of fluid mechanics as it relates to flow over a wing, but there is nothing wrong with Bernoulli's Principle and it fact it is used to daily to solve all sorts of fluid problems.

Alasdair Ryan Posted March 12, 2014 Author Posted March 12, 2014 Over one month later its time for a massive update.... I added the controller for the flashing lights.... Quote
Zoenarr Posted March 14, 2014 Posted March 14, 2014 I'm enjoying the progress of this project! I fuel these planes at my local airport and I look forward to seeing them in technic form! Good luck with the remainder! Quote

Zoenarr Posted March 16, 2014 Posted March 16, 2014 (edited) Thank you,I fly in them between Glasgow and Stornoway. That's great! So you're replicating yours! Our planes travel along the west coast of BC. I enjoy the Saab's quite a bit. Ours are deep blue bottomed and white topped ( a little harder to achieve with Technic) :) Edited March 16, 2014 by Zoenarr Quote
Alasdair Ryan Posted March 16, 2014 Author Posted March 16, 2014 (edited) Not quite because of the colors available,red and white should be very simple and easy to do. It is a shame there is not light blue in a high assortment of parts available. Edited March 16, 2014 by Alasdair Ryan Quote
Alasdair Ryan Posted April 20, 2014 Author Posted April 20, 2014 Some progress...cockpit controls. Quote
OzShan Posted April 20, 2014 Posted April 20, 2014 Looking good so far. Watching with interest :) Quote
Alasdair Ryan Posted April 21, 2014 Author Posted April 21, 2014 Looking good so far. Watching with interest :) Thank you. I am disappointed that it's taking me so long to build it. Quote
OzShan Posted April 21, 2014 Posted April 21, 2014 ... I should now pick up speed,as it should be plain sailing all the way to the end. ... You mean after you tempted fate back here? Haha. Are you planning to leave the fuselage open or build it in? Quote
Alasdair Ryan Posted April 21, 2014 Author Posted April 21, 2014 (edited) All closed in,I am busy with collage which is really sucking up the energy to build. Edited June 29, 2014 by Alasdair Ryan Quote
OzShan Posted April 21, 2014 Posted April 21, 2014 Good luck with the rest of it (and for the studies as well). Quote
Alasdair Ryan Posted April 21, 2014 Author Posted April 21, 2014 Good luck with the rest of it (and for the studies as well). Thanks,I am nearly finished the collage course,so hopefully I will be able to speed up building. A desk and chair for building really helps by the way I did not have that when I first started this plane. Quote
Alasdair Ryan Posted May 18, 2014 Author Posted May 18, 2014 (edited) I have decided to stop building this plane and move on to what I think are better projects. Plus my dad wanted to see the 42025 build (I was going to use that for parts). Edited May 18, 2014 by Alasdair Ryan Quote
