Is it possible to do this...

well, after seeing Jet Man, i wondered to myself if it is possible to build something similar, but go one step further, by completely enclosing the pilot in a blended wing body, and introduce a simple undercarriage (either retractable or with the wheels hidden as much into the fuselage as safely possible), so here i am. i dont plan on building this, at least, not anytime soon, but this is more of a fact finding mission for me.

 

 

now, when i mean enclose the pilot, basically the pilot is in a prone position, controlling the aircraft, which has a minimalistic interior, as there would be little room to move around in (comfort is not a factor on the priority list). the pilot is not actually putting weight on anything below, but rather, being suspended from the underside of the wing, allowing the fuselage to be made of a lighter material. the undercarriage would also be directly linked to the wing, to further eliminate the need for a stronger fuselage. If you know what a typical BWB looks like, youll know that the engines are situated at the top rear part, so for an aircraft like this, small jets would be needed, much like in the link, but perhaps more powerful.

 

so how feasible is this idea, and where could this improve on?

That fella Jet Hombre is an absolute hoot....The first video of him whizzin arround those mountains was really awsome ...I liked the soundtrack too...

As far as enclosing the pilot....hmmmmnnn...I think Jim Bede came pretty close to what your saying...only we're feet first...

and we still catch h...      but thats why I made that documentary....the difference between landing a BD-5 and other aircraft....

Someone will come up with a miniature B-2 ...though...

Ummmm....something like this?

I think the patent has expired, by now.

On the original question, maybe this would be like a scaled-down Messerschmitt 163 that the pilot could lie down in the prone position?  Sould fly pretty well if you kept your speed up, and you could land on the skid like a glider.

Considering that the ME-163 was essentially a scaled-up version of Dr. Lippisch's designs, it looks like we're going full circle....

 (Lippisch DFS-194)

The problem is, most of these small designs involve a pilot flying in the prone position...and that's uncomfortable as all getout.  Take a look at the pilot position of the famous Wee Bee:

Check out the way the pilot's head is cranked back to be able to look forward.  Even with a chin rest, this is not going to be comfortable for any length of time.  The Wee Bee was intended to take the "world's smallest airplane" crown, so all the pilot had to do was tolerate the discomfort long enough to fly once around the pattern.  If your spending the effort to build something, why not ensure that each flight doesn't end with a stiff neck?

A better option might be a plane that places the pilot in a supine position (on his or her back).   Having the chin tucked towards the chest is a more comfortable position.  You could get the drag reduction with less pilot fatigue.

The other issue is...how can I put it...what part of your body you want facing the large, hard, fast-moving Earth below the aircraft.  Take another look at the glider patent I posted earlier, and consider what it would be like having to make a forced landing in a rough field.  I think most of us would prefer to point our gluteous maxima planet-ward, thenkyouverymuch.

yeah, almost like that, but adopting a design similar to this BWB, and probably with a tricycle gear configuration. I guess with such a small design, the only controls available would be the elevons, each controlled with a hand each. also, im sure the rudders and braking systems could still be possible with the standard pedals on most aircraft, but again, with such a small design, would it be possible to fit the basics (basic gauges and radio as well) in this if the fuselage is 3 or 4 meters long?

 

EDIT: for a rough estimate as to the size relative to the person, something like this was what i was thinking about. perhaps a little bigger though, as the rear would get smaller, but this is just a quick thing i threw together.
