WING KIT INFORMATION
- multiple vertical lamination schedule Douglas fir appx 5-6 laminations at root depending on lumber.
- routered pockets integral as span increases forming multiple "I" beam structure(3).
- 9"tallX5" thick at root tapering to tip 3"X3/4" X 25 foot total span.
- top and bottom of spar reinforced with multiple laminations of unidirectional carbon fiber tapering outboard with appx 70% of total span covered in carbon.
- wing ribs are laser cut with spruce cap strips again forming an "I" beam structure.
- the skin is 1/8th ply of a special type glued to the stucture.
- the leading edge is spruce and comes pre shaped in the wing kit to accept the ply skin allowing a smooth skin to leading edge transition.
- Unique fully symmetrical competition airfoil incorporating 29% of chord hingeline aileron design allowing for roll rate in excess of 360degrees per second.
- All ball bearing aileron hinges and full bearing ends on all control rods and push pull tubes allowing for totally smooth and long lasitng effortless control feel.
The kit will consist of the following.
- A pre-laminated and routered main wing spar with carbon caps applied and profiled.
- Main spar has attach bolt pass through mounting lugs pre-installed.
- All ribs laser cut, both main wing and ailerons.
- All trailing edge, leading edge, and aileron spars profiled to shape and to correct dimensions.
- 2 molded fiberglass fuel tanks and installation shims.
- All aileron pivots and bellcranks, bearings and hardware.
- Pitot tube, mount, and tubing.
- All wing ribs feature pre cut holes for running tubing for lighting (not included) and pitot/static lines.
- Tie down block and ring hardware included.
- All required sheeting for wing and ailerons plus all misc internal wood pieces.
The wing has approximately 98ft2 of wing area. The chord at the root is approx 63" and appx 31" at the tip.
The wing being used in the Laser Z-2300 was designed and engineered by John Zimmerman as a replacement for the rebel wing made of composite that failed. The wing was calculated to have a failure range of (1800# acft) 20+ G NOT including the extra strength gained when you consider the sub spars and the rest of the stucture. That is to say, the spar alone is designed to 20G, the total wing structure fully assembled is stonger still. The design was made to be produced with simple methods, however due to the complexity of the spar laminations and the routered pockets forming the "I" beam makeup, the spar is time consuming to fabricate, requiring care and experience to assemble properly.
One of the design goals with this wing was to eliminate the problems found in earlier wings of delamination of wing leading edge and over the spar skins. The extra stiffness of the carbon found in the wing contributes to this greatly. The highest time wing of the same type used in the Laser Z-2300 has several hundred hours total time most being that of HARD acro and competion aerobatics flown by Clyde Cable in his REBEL aircraft.
Many of the Stevens Acros, Haigh Superstars, Lasers and other early airplanes were modified with the inclusion of carbon spar caps and 12-14 foot long (6-7 foot on either side of C/L) vertical plywood laminations on the front and rear faces of the spar. This served to add stiffness to the root of the wings where they were flexing. The first Steven Acro / Laser I owned was modified this way by John Zimmerman using techniques and practices he developed for his wing. That Stevens Acro could be flown at extremely high G(9+) and staring at the wing no evidence of flexing was aparrent and during hard pulls the ailerons continued to function fully with no added binding due to wing flex. I have flown the Zimmerman wing on J.P. Thibodeau's Laser Z-300 and repeated this exercise several times with the same excellent results. In short, the wooden Laser Z-2300 wing pulls tons of G at any speed (like a pitts) and rolls well.
The Zimmerman "Laser 2300" wing is very stiff and stalls clean and predictably allowing awesome spin entries and great naps! It is far easier to pull G than with an Extra at any given speed and way less likely to break loose (bobble) than a Sukhoi, Extra, or even a Pitts!
This wing design is currently flying on 5-7 aircraft. The wing has no flex visible when performing hard aerobatics due to the stiffness of the carbon fiber and the overall rigidity of the multiple "I" beam internal spar structure.
Wing flex at high ROLL rates has never been a problem I have heard of, But wing flex limiting roll rate at high G has been a problem on the earlier "COMPOSITE" wings as mentioned above.
