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 altimeter’s 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 rocket’s 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.
