SoAR 2015 Contests

Contest Calendar

Triathlon

This competition will consist of three contests using the same rocket:

1. A engine target altitude 250 feet as measured by onboard altimeter
2. B engine streamer duration, best time over 30 seconds
3. A engine parachute duration, best time over 45 seconds

The minimum length of the rocket will be not shorter than 15 inches from tip of nose to tip of fin or engine mount.

One section of the rocket must be nine (9) inches of BT-50 body tube.

The same rocket will be used for each of the three contests. Only minor repairs will be allowed on the rocket between flights. Minor repairs are fixing fins at the field or reattaching shock chords etc. No additions other than recovery parts or engines are allowed.

Scoring will be as follows: Each contestant will be given 100 points to start. For the A altitude, points will be deducted for each foot above or below the target altitude with no more than -100 points per contestant.

For the B streamer duration, each contestant will be given 1 point for each second over 30 seconds of total flight time. Total flight time is measured from liftoff to touch down of the rocket.

For the A parachute duration, each contestant will be given 1 point for each second over 45 seconds of total flight time. Total flight time is measured from liftoff to touch down of the rocket.

The contestant with the most points after the three contests will be the winner.

B Cluster

The B cluster contest will be a target altitude contest. The rocket construction rules are as follows:

1. Must have two B impulse engines
2. Total empty weight should not exceed 4.6 oz.
3. Minimum rocket length of 20 inches.
4. Minimum body diameter will be BT-60 (1.63″ diameter) body tube.

The Target altitude for this contest shall be 400 feet as measured by on-board altimeter.

Scoring will be as follows: Each contestant will be given 100 points. Points will be deducted for each foot above or under the target altitude. A successful flight will be if both engines are fired and the rocket returns undamaged.

A Super-Roc

A super roc will be built with a minimum of a 18mm engine mount and be between 75 and 150 cm in length. The contestant with the highest altitude and no damage to rocket will be the winner.

EggLoft

This will be target altitude competition with the addition of a grade A large hens egg. The rocket specifications are as follows:

1. Payload must be three inches of BT-80 (2.6″ diameter) tubing.
2. Egg will be positioned vertically.
3. Must be a single engine rocket.
4. All parts of rocket to stay attached

The target altitude will be 600 feet measured by on-board altimeter.

Scoring will be as follows: Each contestant will be given 100 points. Points will be deducted for each foot above or under the target altitude. A successful flight will be if the egg is returned with no damage and the rocket can be flown again.

B to A Two-Stage

This will be a two stage rocket with a B booster stage and an A sustainer stage. The recovery method will be streamer. This will be a streamer duration contest. The rocket specifications are as follows:

1. Minimum length of 21 inches measured from tip of nose to end of booster stage.
2. Minimum diameter of body will be BT-50 (0.976″, or 25mm diameter).
3. Streamer recovery for sustainer, tumble recovery for booster.

Scoring for this contest will be one point for each second of total flight time measured from lift off to touch down, over 30 seconds. Highest score wins.

Low Altitude D

This will be a target altitude and streamer duration contest with a D impulse motor. The rocket specifications are as follows:

1. Minimum diameter body tube will be no smaller than BT-80 (2.6″).
2. Maximum weight will be no greater than 10 oz. empty.
3. Streamer recovery.

The target altitude for this rocket will be 800 feet measured by on-board altimeter.

Scoring will be as follows: Each contestant will be given 100 points. Points will be deducted for each foot above or below the target attitude. A point will be given for each second over 30 seconds on total flight duration measured from lift-off to touch down.

A Helicopter Duration

This contest will be a total flight time duration contest. Each contestant will build a helicopter recovery rocket that will fly on an A impulse motor. The contestant with the longest flight time measured by the time from lift-off to touch down will win. A successful flight will be one that launches and deploys the rotors and lands in such a way that it can be flown again.
