Good in theory... but not so good in practice?

Found some concept art.I"m guessing it looks *sort* of okay from an aesthetic point of view, but I"d be interested in hearing what the seasoned professionals have to say about the practical ramifications of such a design?

[asra]

I dont see why it wouldn"t work. If it hangs in the 8-12 deg nose down I reckon it will fly, just have to retrofit some kind of instrument panel.

Can you say Faceplant!

[quoj]

Ah... okay.... I"m .. ah... I"m not sure what you"re meaning by "faceplant" but... well, okay..

[asra]

Faceplant = **** over ***...bury your face in the dirt etc etc

[quoj]

Yeah, I got that part. I just wasn"t sure how it pertained to this design.

Having built a few weird designs over the years I may qualify to comment.The tail looks a bit close and a bit small to me. Fix that and if the COG/TL is in the right place I see no problems.(Apart from no flight instruments)

[quoj]

Thanks Murray.Yes, I"ve seen some of your "weird designs", and I"m sure that you don"t end up as the Head Cheese without some hefty experience (... maybe a TIF or two??

[asra]

"Head Cheese", "Hefty experience","Word would definitely carry some clout" : Have you got the right bloke?

[quoj]

Come on, Murray.Don"t be modest!

[dineshkkk]

The simplicity of the design is commendable.

Having those 2 large wheels up front would act like large fins. Worst case, it may want to swap ends. LOL

Looks good to me, just needs an engineer to check the statics and dynamics. The mast does look awfully short to me though, from a stability perspective.

Hi Quoj,The pictures are certainly a snappy piece of concept art. I am not on the forum much, probably spending far too much of my spare time concerned with gyroplane thrust lines etc as I wade through the hundreds of fleet survey responses.My "informed instinctive reaction" to the side-view image is that it"s a superficially appealling design, although I would consider that the front wheels should be reduced in diameter by 1/3 and replaced with spoked wheels and the spats should be abandoned. The engine and propeller axis needs to be raised spinner-upward by 10 to 15 degrees; the vertical stabilizer needs to be increased in height by 70% and the taper of the rudder to be not so severe; the horizontal stabilizer needs to be relocated so as to be level with 1/3 prop blade span down from the prop hub; the snake-tongue tail skids eliminated and replaced by a wheel; the mast needs to be raised a little, those strange triangular elbow-knocking fairings need to be eliminated; some form of minimal instrument pod needs to be fitted; and, a single safety skid would need to be fitted to the front under the rudder pedals to safeguard against a nose-over - and, of course - some form of throttle quadrant needs to be fitted!With all that said, after all these mods it might become practical.Cheers,Mark ReganMelbourneASRA Board MemberASRA Technical Manager
