Nosecone Ejection Test:
The Nose ejection was test results were as follows;
|Ejection Charge [grams]||Ejection Distance [ft]|
* This test included both charge standoffs inside the recovery bay being full of 4 gramms of black powder.
The Setup used was to fill a single charge standoff cup with black powder and test the nosecone ejection. This would ensure that if one E-match failed then a single ignition would still be able to safely eject the nosecone. The E-bay forward bulk head was inserted and attached to the forward airframe section, creating the sealed expansion chamber i.e. Recovery Bay. An E-match was then routed through the standoff and inserted to the charge cup. Black powder was measured out to a tenth of a gram and poured into the charge cup, covered with tape, and then the parachutes, nosecone and shear pins inserted. the airframe was rested upon a small towell to give it a slight angle around 5 degrees. A 9 Volt battery was then used to provide the ignition.
