Canard/Delta Wing glider?

Has anyone ever seen a delta wing shape glider? Or ever flown one? I ask because I'm thinking of building a glider that would have to withstand large accelerations as a way to put itself into orbit....i mean, the air.

you could try a pibros... its a very quick FFF build, and flies nicely! now i'm just curious how you are going to create this large acceleration?

Scaled version of this...



I have alot of estes rockets left over from when I was 10. Also have a very large rocket that could turn into a glider type plane. Probablly won't have a very good glide slope, but thats ok. I'm mainlly doing it to experiment/tinker.

Thats it!!!!

Did you make that, or is it a kit?

I'd like to try and make mine from "scratch"

It's a plan for a slope glider, available from RCM magazine. Check their web site, they'll be more than happy to sell you the plans.

its not that simple,in fact ,in order for the rocket to keep from trying to chase its tail ,you need to have the c/g somewhere near the nose while under thrust which makes for a very poor glider

try to contact a local rocket club for advise,there is usually one guy in each club that has played around with rockets on gliders

I routinely launch my 36" delta wing at speeds up to 150 mph.
with a 1/2" HoseMonster bungee. It achieves that speed in less than 1 second.
That is much more force than you will see with the rocket unless you are using
J-engines or larger.(bungee imparts 35 to 40lbs. of pull) I have seen the plane
launched with an Aerotech reloadable motor. (21oz. thrust/9sec.) and it flew
very well. It is EPP and will weigh about 12oz. with standard tape construction.
It can be made lighter with a matrix of .015 or .020 carbon rod.
It thermals very well once you are use to flying it.

Thanks aero,

Do you have a pic of that plane? You said it was about a 12oz plane and 36" wide, but do you know the total wing area? I think that might help me in making a good prototype model to test fly (not RC, just ff glider).

That fact that its out there is encouraging, now I just have to find time between classes to build some of this stuff.

There are pics on my site, it has about 345sq.in. of area.
If you were trying to work cheap and disposable, you could build a pibros.
My delta wing has the same plan form, but it has a definite foil that
is suited for the speed range and loading.

Estes made a kit of a canard that was a rocket launch RC glider. I built one years ago and flew it with a cox 0.49 in place of the rocket. It flew well until I tried to use a rocket motor. To trim it with the 0.49 it had a lot of up elevator. I assumed that this was going to be a problem so I returned it to what looked to be neutral and let it rip. When nosed over in an arc with about a 12 foot radius and smashed into the ground. Before I could react my plane splinters with a still burning rocket engine stirring them up.

I still have the pieces and have glued them to together in an attempt to slope soar it but it really need rebuilt from the ground up. There is still enough left that I can get some dimensions from it if you are entrusted.

Was it this? This is an RCM plan that was kitted by Estes as the Astro-Blaster. It's RCM plan # pl-1148

what you have here look incredibly like an XP-55 Acsender

WWII There were only three of the ever mad ever production

There area couple of things about this plane that puts it into that ID catagory

1) front cannards
2) mainwings where they are

The verticals on the main wingtips on the original are moved in about 20% of the from the end also, there is another vertical set of fins that is missing on this model that was on the fuse just in front of the pusher prop

I think the similarity ends once you get past the swept main wing.

here is the estes rocket grlider.. not canard though..but very cool.. may give you some ideas... more plane like....http://www.hobbylinc.com/htm/est/est2201.htm ... saw a video of somewhere on the web... leaves the pad in a hurry.. blink and its gone!

Burger... I have actually gotten back into the rocket thing... contests are quite fun... spot landings.. designing your own and all use the same motor to see can get max altitude.... slowest descent, who can lift same weight the highest. etc etc.. all ages participate which is the neat part 40 yrs olds next to some whipper snappers..
