Rocket Glider Duration

« Duration Competition
35.1 Scope
Rocket Glider Duration comprises eleven events open to any single-staged model rocket that returns to the ground in stable, gliding flight supported by aerodynamic lifting surfaces which sustain it against gravity. Entries whose gliding surfaces are made of flexible materials (e.g., plastic film or cloth) are prohibited from this event. The purpose of this competition is to achieve the longest flight duration time.
35.2 Qualification
During the recovery portion of the flight, the entry must achieve a minimum of a 1:1 glide ratio at some point to be considered qualified.
35.3 Disqualification
Any entry that descends with parachute and/or streamer recovery device(s) attached must be disqualified. Any entry that separates into two or more unattached parts, or ejects its motor must be disqualified.
35.4 Classes
This event is divided into classes based on the permissible total impulse of the motor(s). The following classes of Rocket Glider Duration are established:
