Daisy Cutter 60

***UPDATED WITH NEW PAINT JOB 10/5/2012***
New paint job (starting at post #546)

***UPDATED WITH SPECS AND PHOTOS 11/12/2010***
Current Specs:
Wing Span: 60"
Wing Area: 480 sq.in
Wing Loading: 60oz / sq.ft (58oz-62oz)
Total AUW: 192oz
Airfoil: HSNLF(1)-0213


Latest specs, throws and CG

Tales from the Maiden
***END OF UPDATE***



(From original post)

I have decided to spend a little time working on the Daisy Cutter 110 design and will post any progress that accidentally happens. I have a busy schedule so it may take the better of 2 or 3 lifetimes to complete the basic design. If I can get a reasonable design hashed out by mid summer, I may make a bagged prototype to see if there is any potential in the design. So far, I have settled on the name and wingspan. If she evolves into a true contender, I plan to incorporate anti-shock bodies and an area-rule fuselage . For now, I plan to enjoy designing a plane again since it has been 15 years+ since I put a serious project together. I have included some preliminary rough crayon sketches of the incompleted planform and a candidate airfoil section. I will update as I progress.

For kicks, here are some rejected ideas that will not be incorporated into the design:
1. Undercarriage
2. Cockpit with fuzzy-haired pilot
3. Leading-edge ailerons
4. Swing wing
5. Balsa wing mounting blocks
6. Kazoos mounted as servo covers
7. Canard
8. Biplane configuration
9. Lipos
10. CO2-cartridge-powered "landing bag"

Some things I am considering that I believe have proven their worth:
1. Wingspan no less than 100"
2. T-Tail or X-Tail
3. High Wing-Loading
4. Ability to use "everyday" servos and power systems
5. Fuselage shaping to reduce/eliminate stress points

Some things I would like to try since nobody else has that I know of:
1. Metal-Mesh in the layup for enhanced radar cross section
2. Onboard radio TX sending out "Song of General Kim Jong-Il" over the airwaves (update: apparently some clowns stole my idea and launched a satellite that transmits this song )

Current Specs:
Wingspan: 110 inches
Length: +-80 inches
Wing Area: 945 square inches
Tail Configuration: T-Tail
Wing Configuration: 1-Piece, Polyhedral

Current Tasks:
1. Incorporate planform changes into wing model (done!)
2. Improve wing thickness modelling
3. Improve wingtip modelling (almost done)
4. Move wing saddle back from nose additional 2" (done!)
5. Model H-Stab
6. Model V-Stab
7. Refine fuselage shaping. Shorten fuse and tail moment. Narrow fuse at wing. Widen fuse at tail. Ovalize fuse at tail.
8. Blend V-stab and fuselage
9. Build it
10. Fly it
11. Refine it

How about a layer of Texalium glass, you know the stuff is impregnated with aluminum. Has anyone tried that before?

Aaron,

Looks like you're quickly getting the hang of the 3d package! Looking good...
Will watch with interest!

I bought a roll of some light texalium with the intent of using it for radar improvement but I checked it thoroughly with an ohmmeter / continuity checker, and got nothing. Zilch!

I read somewhere that someone else tried it and got good conductivity. Perhaps my stuff was too lightweight? Anyone got a bead on the 'right stuff'?

I like that I didn't see 'swing wing' design concepts being eliminated. You must be shooting for high mach#s

I'm not sure if conductivity means much,,carbon is very conductive and it masks the radar..

I did see some X-country ski boots that had a Carbon/Titainium weave used on them,,wonder what that stuff is called.

I sure would like to have a roll of that stuff.

Aluminium candy flake car paint in the outer layer of the layup. Big flakes of ally. Yum.

BTW, nice to see someone else creating a new plane. Look forward to seeing your slant on it all.

Dean, you mean like this?

Kinda hard to see but the plane I have on the bench now has aluminum foil in lots of places! Hope to report the results soon.

Sorry Aaron, don't mean to distract the thread...

Wasn't sure which list to put that idea on just yet

Spencer,
Even if the foil in your layup doesn't improve radar cross section, it is still worth the effort for the killer trippy finish effect!

Titanium/Carbon

I found a pic of the Boot that has the new Titanium/carbon stuff.

Wish I could find a roll of the stuff,,guess we could check with the manufacturer.

I've had these boots in my hands and the material is super strong.

Anyway here's a pic.

Nice fuz, but where are the wings?
Suggest you name it "Hermes DS"

I represent Alpina in the Rocky Mountain Region and can ask Alpina if we can find out more info on the TCS Cuff. It is very strong and light. Our top athletes use it on the world cup with great results. The material is currently in Slovenia where the boots are made.

Adjusted wing saddle location. Wing still needs planform work, refined foil and dihedral.

Getting somewhere...

Zeroing-in on distinctive wing shape...

(This one is 110" span and 945 square inches area)
