Here's a short video explaining the difference between the free airstream relative wind and the local relative wind and why the difference between the two results in induced drag. Visit www.rodmachado.com

Never understood why induced drag decreases in ground effect. Thanks to this video, I now do!!

Ps- I flew my Mooney M20J from Toronto to New Mexico: first time flying to high elevation airports. Your video on density altitude and how to lean a constant speed most likely saved me from an accident.

Thanks - two areas I would appreciate coverage in any course are . How the center of pressure moves around on the wing when ailerons are deployed ( laterally toward tip of downgoing aileron and slightly aft with inboard and slightly forward on other wing ) , then when flaps deployed ( inboard and toward trailing edge ) . Secondly why AOA is higher on inboard wing in a turn . Thanks .

there are so many people having aviation channel, but none of them are even close to Rod machado, thanks rod, and i hope you you make a video regarding to upwash and downwash exclusively .and could you explain what you mean by Local relative wind?

@elliottdiedrich30682 жыл бұрын
The way that the illustration is demonstrated, it shows the air rising up to strike the underside of the wing like a constant updraft. That would sure be good for fuel economy because it would be like being in a constant descent even though you are flying straight and level. How do you get the air to suddenly rise toward the plane? Also, why do you show that the lift is vertical on a normal angle of attack but tilted back on an increased angle of attack?
@Flight-Instructor2 жыл бұрын
Greetings: The wing's overall pressure distribution results in the upwash ahead of the wing. The portion of lift that's vertical is often referred to as "Effective Lift." The portion tilted aft is the wing's Total Lift. The tilting aft of the total lifting force results in increased induced drag.
@nalamobil3 жыл бұрын
I still got one problem: How does this explain the effect of aspect ratio on induced drag?
@willwillis67843 жыл бұрын
Hi, as aspect ratio increases, induced drag decreases because the wing will be less effected by wingtip vortex the larger the aspect ratio, then obviously reducing induced drag because there would be less downwash from the wings and therefore the direction of lift will be 'tilted back' less. I hope this helps a bit

@@Flight-Instructor "According to the 9/11 Commission Report, as Flight 77 was 5 miles (8.0 km) west-southwest of the Pentagon, it made a 330-degree spiral turn clockwise. At the end of the turn, it was descending through 2,200 feet (670 m), pointed toward the Pentagon and downtown Washington. Hani Hanjour advanced the throttles to maximum power and dove toward the Pentagon. While level above the ground and seconds from impact, the wings clipped five street lampposts and the right wing struck a portable generator, creating a smoke trail seconds before smashing into the Pentagon.[39][40] Flight 77, flying at 530 mph (853 km/h, 237 m/s, or 460 knots) over the Navy Annex Building adjacent to Arlington National Cemetery,[41] impacted the western side of the Pentagon in Arlington County, Virginia, just south of Washington, D.C., at 09:37:46.[42] The plane hit the Pentagon at the first-floor level," en.wikipedia.org/wiki/American_Airlines_Flight_77#Crash

I discovered that Parasite drag is produced by VERTICAL surfaces and Induced drag is created by HORIZONTAL surfaces, for example when the Flaps are at 0 degrees they produce Max Induced drag and Min Parasite drag, at 90 degrees Min Induced and Max Parasite drag and at 45 degrees in the middle of both. Please let me know if you think it is a valid observation. Thanks

Induced drag is a squared function of lift coefficient.

@mattematsson5544 жыл бұрын
Slow speed increases induced drag. It creates vortex around the wingtips which disturb the airflow (lift) over the wing. The ground effect "cuts" the vortex and the airflow/lift increase. Some say that the plane is "cushioned".
