Facetmobile - A Lifting Body Full Scale


<http://members.aol.com/slicklynne/facet.htm> takes you to a marvelous site. Barnaby Wainfain tell us about the "Facetmobile.

He flew from So. California to Oshkosh Wis. to the EAA Convention and got First Place in his Class. I wish I knew how to print a LIVE address. Sorry , copy and paste.

I built a balsa and ply model of the Facetmobile 44 inches long and 21 inches wide.. It has two wheels and a tailwheel. It is remarkably light weight. It is nastily made of 3/16ths balsa square sticks. I used Rudder and elevator. With the dihedral I built in it is super stable.

I flew it with an 09 glow, I think with micro radio the Speed 400 or the \\\eskay 400 TX//// would be fine. It is a work in progress. Just had maybe 30 flights , with no mishaps. It like to fly slow....maybe 18 mph.
It will not stall from a normal level flight , pull that stick back and keep it back - the thing starts to sorta fall lif the falling leaf- searching for a comfortable attitude. In a 10 mph wind I can almost come straight down.

Lifting Bodies are PHUN ! Have any of you any interest in the Lifting Body? Show pics please. The shuttle is a lifting Body. A sky diver is a lifting body.

Some one draw up one for Speed 400 or small AXI.

From Barnaby Wainfains Web page.
Conclusions From The NASA PAV Study:

Flight tests of the FMX-4 have shown that a faceted low aspect ratio all-lifting airplane can have good flying qualities, compatible with a modest level of pilot skill and be highly departure resistant.

A faceted low aspect ratio all-lifting airplane can have performance comparable or superior to a conventional airplane having the same power carrying the same useful load.

Due to its intrinsic structural efficiency, a low aspect ratio all-lifting airplane will have an empty weight that is approximately 55% of that of a conventional airplane having the same useful load and cruise performance.

The low aspect ratio study airplane, with 80 horsepower has up-and-away performance comparable to the current-generation all-metal trainers powered by the 115 horsepower Lycoming O-235. It is significantly superior to the conventional all-metal airplanes in terms of takeoff distance and rate of climb.

The overall system-level transport efficiency of the low aspect ratio study airplane is significantly superior to the classical riveted all-metal airplanes, and comparable to a modern, molded all-composite machine.

The low aspect ratio all-lifting configuration composed of flat panels is well suited to automated manufacture of components, and will require many fewer hours to assemble than a conventional configuration.

The flat-panel construction of the study configuration allows it to take advantage of cost savings available from use of CNC high-speed machinery without the need for the airframe manufacturer to purchase or maintain expensive machinery or tooling. Large cost savings can be realized even at low production rates.

The non-recurring cost of tooling and specialized machinery required to fabricate the parts for a faceted low aspect ratio all-lifting airplane and assemble the airframe will be much lower than comparable costs for a conventional wing-body-tail configuration.

Due to its combination of light weight, compatibility with automated manufacture, and reduction in assembly labor hours, a low aspect ratio all-lifting sport/trainer airplane similar to the study configuration can cost up to 50% less than a conventional airplane designed for the same mission.

These characteristics are apitizing, and it is so stable... maybe a hover craft but not a 3-D all out. BUT IT IS A SCALE MODEL I have in mind; 44"long and 22" wide. Made of 3/16ths balsa. Weight est. at ~24 ounces. 600 square inch area!

Well "teacher" ,instead of telling someone to do something for you take a minute or two to do your own research.

I have no dislike for teachers nor am I antisocial, I just don't like you. You have constantly demeaned, put down and made snide remarks to 90% of the people on this board that you have made contact with. I am not sure if people walk around kissing your feet(or other parts of your anatomy) in your normal life but here you have shown yourself to be a small minded bully. There are 12 y/o kids around here that have shown more manners and commons sense than you have in your short time here.

Either way you have been told this by more people than me so I am done.
Welcome to my ignore list.

BTW:"do you hate the teachers you had because you couldn't learn"
Shucks you caught me, I'm just a big dumb hillbilly. You got me there,what a zinger.

Logical Psycho. It matter not wheather you LIKE me or not. I am not here to LIKE people. I am here to glean information and to enjoys different ways of explaing the same old thing that was explained 50 years ago. I just happen to LIKE airplanes.

L. Psyco, you accuse me of several rude actions and LOOK WHAT YOU JUST WROTE.

By Logical PSycho, "Well "teacher" ,instead of telling someone to do something for you take a minute or two to do your own research." I could say, You idiot where did I ask anyone to do research for me? Where? Show Me! But I will not resort to snode remarks such as your recent ones.

I am her for fun. You will not see another post directed at you.

Logical Psycho. Why don't you show us that you reallly do know some aerodynamics or even something about radio. Please contribute something we all could benefir from. Lastly, when someone accuses another of some thing they bettere be ready to show their evidence or just shut up.

You are her who?

As for evidence of the things I said about you I present

As for my contributions I am here to learn, share and have fun with people that enjoy this hobby, not be berated by a sad old man that needs to constantly put people down as stupid or tell everyone how smart he thinks he is. Not to mention I answered your same attack in your last thread and you simply ignored it.

Lastly here are some quotes to fellow members from this "gentleman" for those who don't feel like reading through the threads linked above.

Quote:
"I expected all of you men who claim to be aircraft designers and pilots to jump on that with both feet. Guess basic H.S. Physics didn't interest many of you."

No that is just a picture from their site...

No ideal how it flies but it looks like it should be a decent flier.

Boomerace built one.. here is the build thread.

The EAM Facetmobile flies fine...was underpowered on the original IPS GWS powerplant. I upgraded mine to a Twin IPS A drive right after I got it and it flew well...works GREAT with small 3S outrunners of about 100 watts.

You kids play nice in here, now.

The Shuttle is not a lifting body; it uses a delta wing structure with a vertical tail.

A skydiver is not a lifting body, either; having been a skydiver, I can tell you from experience...I have never experienced lift while skydiving...just gravity!
