The TARC rules for 2022-2023 have been announced (see www.rocketcontest.org). Major requirements include:

• Rocket must carry one raw egg (any orientation)
• Rocket must carry a Perfectflite Pnut or Firefly altimeter.
• Target altitude is 850 feet for qualification flights.  At finals, target altitudes will be 825 feet and 875 feet.
• Target duration is 42-45 seconds for qualification flights.  At finals, target durations will be 41-44 seconds and 43-46 seconds.
• Rocket length must be 650 mm (25.6”) or greater.
• Rocket mass at liftoff, including motor(s), must be 650 grams (22.9 ounces) or less.
• Rocket must have two sections, one for egg & altimeter and one for booster.  The two sections must come down separately, each section with its own parachute.
• Motor(s) maximum total impulse = 80 N-sec (F motor).

Safe operations are our top priority at DART launches. Requirements for flying TARC models at DART launches include:

• Rail launch (6′ or longer) is required. 1/4″ launch rods (or similar) are not acceptable.
• Positive motor retention is required. Taping motors or friction fit is not allowed. [Note: this is already a TARC requirement, and we will enforce this requirement.]
• Minimum stability margin of 1.25 diameters is required. Inadequate fin size can lead to dynamic stability problem that adversely affects trajectory and performance.
• Simulation report (Rocksim, OpenRocket, or similar) shall be presented documenting mass, CG, CP, max altitude, and time to apogee (i.e., make sure motor has appropriate delay).
• Fabric parachutes are required. Plastic or “garbage bag” parachutes are not permitted.
• Safety check. Demonstrate motor retention, shock cord attachment/strength, proper fit of coupler joints, etc.
• Follow instructions from DART range personnel. Decisions by the DART Range Safety Officer are final.
