Do you Dual-Deploy?
Southern Area Rocketry (NAR Section 571) would like to invite everyone to a contest we are sponsoring in March. Please come on over and show us that you know DD better then we do .you probably do. Please see www.soarrocketry.org for details and updates.
SoAR's Dual Deploy for Model Rockets Contest
Date: March 27, 2010 All launches must occur during the scheduled launch window.
Location: TurfSouth Sod Farm, Hoschton, GA
Contestants are required to build and fly a model rocket (G motor or less, 3.3 pounds liftoff mass or less) that will use dual-deploy (altimeter based) recovery. The winner is the entrant whose rocket goes the highest and lands closest to the original launch pad.
Rocket must be within Model Rocket parameters:
-Total Impulse must be G or less
- Weighs no more than 1,500 grams (53 ounces), including the propellant
- Rocket must use Electronic Dual-Deployment for recovery. The intent is to encourage entrants to use altimeter based deployment for apogee/drogue and main parachute deployment. Motor based ejection for apogee/drogue deployment backup is permitted, but the altimeter apogee event should still be used.
No parachute/streamer is required at apogee; however, ballistic return from apogee is considered unsafe and will constitute a DQ. Some process for reducing velocity from Apogee to Main must be employed
Only commercially available altimeters will be allowed. Modifications to a commercially available altimeters program or design are not allowed
Final descent under the main parachute must not be more than 22 fps. All recovery devices must function as designed (yes, a tangled chute constitutes a DQ, but motor based ejection at apogee is O.K). Descent rates will be computed based on gross weight and main parachute size and design
Damage beyond ¼ zipper or paint scratches constitute a DQ
Score is determined as the maximum altitude reached (in feet) divided by the rockets landing distance from the original launch pad (in yards). The judges will provide a laser range finder for the landing distance determination. The rocket must be returned to judges table for the altimeter reading
The entire rocket must be recovered.
High score wins the collected entry fees. You must be present to win.
An instructional video series on dual deploy that should be usable in model rockets is available from Apogee Components.
Entry Fee: $5.00 per rocket entry (multiple flights allowed).

That one 'Must be present to win' rule gets me all the time..Dang! Curious how high is the waiver at the Hochston field?
