  •  That's a whole chapter unto itself (15+ / 0-)

    We have to be in motion first before any of that takes place.

    If the pilot's good, see, I mean if he's reeeally sharp, he can barrel that baby in so low... oh you oughta see it sometime. It's a sight. A big plane like a '52... varrrooom! Its jet exhaust... frying chickens in the barnyard!

      But my basic suggestion is to include an illustration that ties together the concept of the 4 basic forces such as is shown in the page in the second link.

      And as much as I dislike the purpose of stealth military aircraft, I'd also suggest you include one of these flying wings when you get to wing and control surfaces; aerodynamics reduced to the essentials.

        Wouldn't it be nice if we let Major Kong write his very informative diaries without trying to influence the direction?  knNko, if you're dissatisfied you could write your own series on aerodynamics, couldn't you?

      If you go to one of those dinky little airports way out in the middle of nowhere the manager might be able to tell you about times when the winds get so strong the little things like the Cessna 150s and Aeronca Champs are floating in mid air.  The only thing that keeps them from blowing away are the tie downs.

    •  there was that verticle lift rotating 4 engine (1+ / 0-)

      bus that Mr Finals posted recently, that thing was terrific!

      and said to be the only 4 engine plane to carrier land and takeoff.

      The whole wing with engines rotated to vertical and the plane could, at great expense lift and hover. Most times they said they rolled a little bit and some intermediate angle so as to get lift too.

      Now imagine four jet engines pointed straight down.

      Now imagine many fire trucks.

      •  There's another 4 engine plane that did so (4+ / 0-)

        If you're talking about landing and taking off from an aircraft carrier, there was a series of tests involving the C-130 Hercules a ways back. No need for rotating engines to hover - just flying it on and off.

        They demonstrated the concept, but it was decided not to pursue it. The video below gets to it around 2 minutes in. (Note - the Navy no longer operates Herks on skis. The 109th out of Scotia, NY does it now.)

        •  yeah. I thought maybe, thanks, amazing C-130 (3+ / 0-)

          but they didn't continue it it seems?

          and the pilots had carrier but no four engine experience.
          and the video of the F-86 on the KC-130 tanker..another terrific plane.

          The video shows the deck crew ducking down as it lands, I bet the first couple of landings were tense..thanks for this.

            They had to clear the deck of everything to make room for the Herk. That would be a major headache for a carrier trying to do normal operations. That plus the right wingtip of the Herk only cleared the Island by a few feet.

      His development of Energy - Maneuverability theory, obsession with drag polars, etc. can make for some heavy going - and that's without the math.

      Nice job on keeping your start on this at a basic level.
