Katana 4 – Material Weights

I’ve weighed all the components of the rocket. I’ve tabulated them below.

To identify which parts I’m referring to, I’ve included a picture of the components on the installation instructions.

Booster Airframe: 1494 grams

Motor Mount: 443 grams

Payload Airframe: 721 grams

Nose Cone: 349 grams

Nose Cone Coupler Tube: 222 grams

One Top Fin: 151 grams

One Bottom Fin: 113 grams

Bridle Strap: ~40 grams

Avionics Bay Fibre-Glass (52mm length): 60 grams

Avionics Bay (Wood + Bulkheads + threaded rod + nuts + washers + eye-ring bolts : 395 grams

Nose Cone Bulk plate + Eye Bolt + Nut: 90 grams

Avionics Bay Coupler (275 mm): 322 grams

Centering Rings (2 of these): 15 grams

We need to know these weights so that we can create a simulation file in Openrocket to simulate the flight of the rocket.

 

NOTE: I’ve opted to use a different sled arrangement in the Avionics Payload. Wasn’t happy with the one provided. The weights are almost the same, just a few grams lighter.
