propellant tank with upwards-moving piston (to the right, as pictured), after manual fueling and prior to oxidizer loading operations. The fuel tank is sealed and the rocket may be handled without hazard as long as the fuel valve is kept closed. https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/42252c8b-0df7-418e-8502-d4a71f2afa78/HCR-5100+Propellant+Tank+Explainer+Ox+Fill.png Propellant Tank - Make it stand out Stacked propellant tank with upwards-moving piston (to the right, as pictured), at an arbitrary time during oxidizer fill. The static vent is located just below the oxidizer side of the propellant piston (on the left of the piston, as pictured). Even though the oxidizer tank is sealed, the rocket is hazardous at any time when pressure or oxidizer are present. No personnel are allowed to be near the propellant tank at this point, and must remain away until it has completely depressurized. https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/8014b515-ffb3-4d05-b154-103e5dd3c92e/HCR-5100+Propellant+Tank+Explainer+Start.png Propellant Tank - Make it stand out Stacked propellant tank with upwards-moving piston (to the right, as pictured), prior to starting operation. Note that in reality, the propellant tank must be upright relative to gravity, so that the oxidizer (blue) drains to the outlet at the bottom (on the left, as pictured) and fuel (red) drains to the outlet at the top (on the right, as pictured). https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/5eeaf2b1-18b7-4757-a910-b6b7111fcbf7/HCR-5100+Propellant+Tank+Explainer+Middle.png Propellant Tank - Make it stand out Stacked propellant tank with upwards-moving piston (to the right, as pictured), at an arbitrary time during operation. In a stacked tank configuration, the piston moves upwards to force fuel out while oxidizer drains. The drained portion of the tank is replaced by gaseous oxidizer. https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/4eeb6913-9f61-4e2b-b025-2c75277a9a64/HCR-5100+Propellant+Tank+Explainer+End.png Propellant Tank - Make it stand out Stacked propellant tank with upwards-moving piston (to the right, as pictured), after exhausting all liquid fuel and oxidizer. Once all liquid has been expelled, the remaining pressurized gas discharges through the oxidizer outlet. https://www.halfcatrocketry.com/interfaces daily 0.75 2024-05-31 https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/4cce87b9-de7b-4b74-a8fd-e939623e7478/HCR-5100+2x2+attachment.png Interfaces - Make it stand out 2x2 attachment between thrust chamber assembly and propellant tank, with attached fins (valves and plumbing omitted) https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/23169c2d-a5d1-48eb-974d-d768eeba6b6c/HCR-5100+Clean+Airframe+Mating.png Interfaces - Make it stand out Clean airframe mating between fuel tank bulkhead and lower airframe tube, including recovery bulkhead for shock cord attachment (fuel valve and plumbing omitted) https://www.halfcatrocketry.com/fluid-system daily 0.75 2024-05-31 https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/c689cfc0-20cf-4655-931c-7a5d9d1417f5/HCR-5100+SABV.png Fluid System - Make it stand out Servo-actuated main propellant ball valve (housing highlighted in blue for contrast) https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/4a61b50c-a1bc-42b6-8519-11177dbf77f6/HCR-5100+QD+Section+View.png Fluid System - Make it stand out Flange-Clip QD (clip highlighted in blue for contrast) https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/feb6dd31-c468-4539-a8f4-2aeee45a2f59/HCR-5100+QD+Iso+View.png Fluid System - Make it stand out Flange-Clip QD (clip highlighted in blue for contrast) https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/972e47f3-ef7c-4923-ac59-eb01e7da436b/Old+Half+Cat+QD.png Fluid System - Make it stand out Unsuccessful QD mechanism. The printed sleeve holds onto the release ring so that the QD can be pulled out, however in practice the shock load of launch prevented the QD from disconnecting and broke the tether. https://www.halfcatrocketry.com/fuel-and-oxidizer daily 0.75 2024-05-31 https://images.squarespace-cdn.com/content/v1/60d8d9b060e90a67c5c69db4/04a5c7f7-6898-4155-8db7-c06e80ddeca5/HCR+Fuel+Table.png Fuel and Oxidizer - Make it stand out Recommended fuels for standard liquid rockets.
