Nike Smoke 1/12.4 Scale Model Rocket

thingiverse

The Nike Smoke was a sounding rocket to study the behavior of the horizontal winds in the upper atmosphere. It was developed by NASA in the 1960s based on the Nike booster. This version is a scale 1/12.4 replica that when completed stands 468.5mm (18.44") tall and uses an Estes BT-55 body tube. Version 2 with separate printable fins can be found here: https://www.thingiverse.com/thing:3232768 You will need the following: - 1 x BT-55 203.2mm (8.00") long (flying version) - 1 x BT-20 127mm (5.00") long - 1 x Engine hook - 1 x 304.8mm (12") Parachute - 1 x Shock cord - 2 x "UNITED STATES" decals which you will have to make and print out. Assembly Notes: - I've added pictures to aid in construction. - Use the positioning tool for engine block placement and for engine hook slot position. - It is not necessary to glue the engine hook retainer in place. This way you can remove the engine hook for a nicer static display model. Beware however due to heat from the motor that the retainer will shrink making it hard or impossible to remove again. - I use 5 min Epoxy for the complete build. - To make sure the nose cone and the fin can fit the body tube you might want to print the lower portion of the nose cone first and test fit it to the body tube. If too tight or too loose scale the objects accordingly. You may also only need to slightly sand the shoulder to get a good fit. - See picture for paint scheme (complete rocket white, 3 fins red and one fin yellow). This rocket flies great on B6-4 and C6-5 rocket engines. Download the files only if you are going to start in printing the parts because I might have done some required design tweaks/changes which will be noted below as revisions. I would love to see your results! Please support my work by giving me a tip if you find my contribution useful. Thanks.
