During the test flights in 1945 they just used the outer flaps but never the inner flaps (you might check my blog for an article about the Horten IX). Here is a link:<br /><br />http://1.bp.blogspot.com/-Dq3KtIiEB5E/Tq54WP8RpQI/AAAAAAAAAkw/bnCIQfwAVV4/s1600/Horten_IX.png<br /><br />My opinion is that a flying wing is a bit dangerous and that a conventional design is much more forgiving to pilot errors and similar matters. If you have to use 10 degrees of twist to be comfortable with a flying wing then you should also add the tail (and fuselage) to it since those are the most effective naturally stabilizing factors in a flying device. And who needs so much wing? You need the full lift usually only during take off and landing and most of the time the large wing would only produce drag if that plane is to be used mostly for cruising. A fighter, bomber or high altitude aircraft might need such a large wing but also high lift devices are available.<br /><br />One should do calculations to be sure what is actually most optimal for any given task.Exo Cruiserhttps://www.blogger.com/profile/03559556533503422733noreply@blogger.comtag:blogger.com,1999:blog-8321804912236998273.post-37325017702035962412011-11-13T22:02:43.162+02:002011-11-13T22:02:43.162+02:00Hi Karoliina and at all

Depending on length of flap, sweep,and aspect ratio, you could have a moment neutral flap, in conjunction with elevons. If additional lift occurs in front of the centre of lift of wing, then wing will pitch up, if behind, then it will pitch down. This centre of lift position will change as flap is deflected. Obviously you would prefer a gentle pitch down so that elevons deflect upwards hence increasing wash out and avoiding tip stallingRogue Wavehttps://www.blogger.com/profile/05382787910527606275noreply@blogger.comtag:blogger.com,1999:blog-8321804912236998273.post-13181832230964030842011-11-11T12:17:45.241+02:002011-11-11T12:17:45.241+02:00Hi Robb, here is a link to Amazon.

"Tailess aircraft in theory and practise" by Karl Nickel and Michael Wohlfahrt. Also amount of twist varies with chosen airfoil, sweep, aspect ratio and winglets. Correct use can reduce twist. Have an idea to build a full size flying wing, but about to build RC model first.Rogue Wavehttps://www.blogger.com/profile/05382787910527606275noreply@blogger.comtag:blogger.com,1999:blog-8321804912236998273.post-690875930548642682011-10-31T23:19:47.365+02:002011-10-31T23:19:47.365+02:00Regarding the ease of construction point.

Construction was amazingly simple.<br /><br />I wonder if the ease of construction angle would make the BWB a good option for home builders. If the design significantly reduce the time to build and skill required it would be nice to see homebuilt designs for the technology.Robb Greathousehttps://www.blogger.com/profile/15502333995140400588noreply@blogger.com
