    Bird Strike Testing

    When fired into a flat plate, again there was very little if any difference in the amount of impact damage. Both birds shattered into a zillion pieces.

    Bird Strike Testing

    I saw the show and there was no difference in a frozen or thawed bird. They both did the same amount of damage. When fired into a flat plate, again there was very little if any difference in the amount of impact.

    Flaperon Design mixer help

    Interesting to say the least. I am off tomorrow and Friday (My Saturday and Sunday's) So I will have time to explore all of the above.

    Flaperon Design mixer help

    Thanks SparWeb: I did a Google search and came back with a lot of hits. I have bookmarked several for later reading. I have plans of visiting my home in Indianaplis later this year, so Toronto is not too far out of the way. Darn! There goes my cellphone camera idea. As for Murphy, I have...

    A Mental Challenge for Aero Engineers

    I would like to add my 2 cents worth here. I too am not an engineer, far from it, but as a computer/network/WAN/LAN manager person, we found that communications cable with smooth surfaces was the worse to pull through fixtures, whereas cable with dimples/rough surfaces presented less of a...

    Flaperon Design mixer help

    Maybe some one can answer this question(s). My design calls for nylon bearings, fabricated to fit into 2" O.D. 4130 tubes. Since these involve very low speed rotations, but at times might call for excessive forces, is this a good material or should I use teflon? Is there another product...

    Flaperon Design mixer help

    I wrote to Mr. Heintz a month ago he is most likely very busy and has not responded so I will try De Havilland Canada, and or Murphy Aircraft since they're right down the road in Chilliwack, BC about 300 miles as the crow flies.

    Flaperon Design mixer help

    I was mostly joking about the patent. Too much of a hassle. I just want to get flying. No I have no intention of producing a kit. That too is a hassle, and the liability is not worth it. This has been my dream of many years and as stated, I have built designs of others. There are others...

    Flaperon Design mixer help

    I guess I must have misstated my intentions. I understand the flaperon design has been done before. In fact it was used on the Junkers Ju-87 in World War II. I have studied the other designs as found on the Murphy Rebel, Kitfox and the Zenithair CH701/801. My design incorporates ideas from...

    Flaperon Design mixer help

    Hi: I posted a thread in the AERODYNAMIC section seeking help on a flaperon design. I have not received a response, so I designed my own. I think it looks pretty slick, but looking slick does not mean very much in the air where it really counts. I am not a structural engineer, in fact I am...

    Hi: THanks. I briefly checked out your site at work. I will look at it later when I am off. Tony

    Myth Busters Chicken vs airplane windshield

    I lived in Lavonia, Michigan in the mid 80's and remember a helicopter pilot being knocked cold turkey when hit by a Canadian Goose traveling on the same flight path. Fortunately the pilot had the autopilot on and came too over Lake Erie, or was it the Detroit River? Anyway, there was a lot of...

    Composite sandwich, material type and laod calculations

    Let's get some ground information on the table first. I am NOT an aeronautical engineer. I have built two aircraft successfully and obviously lived to tell about it. Both were built from scratch using plans. I am a private pilot and have been flying since high school (1966). I am checked out...
