Tripoli Minnesota Altitude Record Rules
Tripoli Minnesota Altitude Records
- There are no prizes, only bragging rights.
- Both commercial and research records will be recorded. Commercial records are classified by motor class. Research records will be classified as listed below.
- Any size motor as long as you can fit an altimeter in the rocket.
- Separate classes for single motor, hybrids and clusters / staged flights. For clusters or staged flights, add the total impulse of all motors to figure motor class.
- All results MUST be measured by an onboard altimeter. For altimeters with barometric and accelerometer data, use the altitude derived from barometric data, it tends to be a more accurate indication of altitude. Sorry but no accelerometer only based altitudes accepted.
- Altitude measured in feet above ground level.
- Rockets must be returned in flyable condition.
Things to do for an altitude record attempt.
- BEFORE the flight, fill out two flight cards (keep one) and inform the LCO/RSO that this is a altitude record attempt.
- After the flight, you will need any two of the following to sign-off on the flight:
- Any member of the Board of Directors
- On duty LCO/RSO of the flight
Some more details:
- Photo of you and the rocket – it will be posted on our website.
- 1st 2nd 3rd place of all motor classes will be posted on our website. Each rocket can occupy only one place per class. There’s not much point to having all 3 places in any one section won by the same person with the same rocket, with only 100 feet or so difference in their flights.
