Pee-Wee Payload Competition comprises three events open to model rockets that carry one or more Pee-Wee NAR model rocket payloads. If the model is staged, the payload(s) must be enclosed in the uppermost stage of the model. The purpose of this competition is to carry a payload of given mass and dimensions to as high an altitude as possible and to recover the payload. The Pee-Wee NAR payload is intended to represent an instrument package whose dimensions and mass cannot be modified, but must be accepted as a design constraint.
P25.2 Pee-Wee Payload Specifications
The Pee-Wee NAR model rocket payload is a non-metallic cylinder containing fine sand, with a mass of no less than 3.5 grams. This cylinder shall be 6.2 +/- 0.5 millimeters in diameter, and 70.0 +/- 10.0 millimeters in length. The payload may be permanently sealed to prevent the loss of the sand. No holes may be drilled into it, no changes made in its shape, and no other material may be affixed to it.
P25.3 Enclosed Payloads
The standard NAR model rocket payload or payloads carried in a model shall be completely enclosed and contained within the model, shall not separate from the model in flight, and shall be removable from the model.
The payload(s) shall not become separated from the portion of the entry intend to contain it during flight or upon landing, and the flight shall be disqualified if this occurs.
Following the flight, the contestant shall present his/her entry as recovered and, in the presence of an official, shall remove the payload(s). If the official cannot examine the payload(s), the entry shall be disqualified. If the contestant removes the payload(s) in the absence of officials, the entry shall be disqualified. The official may require that the payload(s) be rechecked if there is any question as to whether or not mass may have been lost from any payload, and shall disqualify the entry if it no longer complies with Rule P25.2.
This competition is divided into classes based upon the permissible total impulse of the motor(s). The following classes of Payload Competition are established:
|Motor Class||Payloads Carried||Weighting Factor|
If the portion of the model containing the payload cannot be returned to the officials, the entry shall be disqualified. Rule 10.4 does not apply.
