Hey everyone,
My setup in my Norad is that my drogue is in the lower body tube, followed by the ebay, and the main in the upper tube. The ejection charge for the main is directly outside the ebay, and it pushes the main chute with all laundry out of the tube behind the nosecone. The ejection charge for my drogue is on a wire and runs alongside the laundry to behind the drogue. When it fires, it pushes the laundry out behind the ebay. Like so:
----------------------------------------------- ----------- -------------------------------- ----------------\
Motor Ejection Canister Drogue | E-bay | Ejection Canister Main | Nosecone >
----------------------------------------------- ----------- -------------------------------- ----------------/
I see a common practice is to mount the ejection charges to the e-bay, which would look like this:
----------------------------------------------- ----------- -------------------------------- ----------------\
Motor Drogue Ejection Canister | E-bay | Ejection Canister Main | Nosecone >
----------------------------------------------- ----------- -------------------------------- ----------------/
Wouldn't this require the body tube to separate below the drogue? The ejection charge would push the drogue down into the body tube while the e-bay ejects, wouldn't it?
I ask because I am always worried that the force of acceleration is going to push the laundry back on the ejection charge, tearing the wires out of the altimeter ports and was wondering if it would work to place the ejection canister directly behind the e-bay.
