Milestones rocket, horizontal flight msl standard day

milestone1: 50\$

create any rocket and fin-form form you want, od 4mm, length 60mm. show the "coanda" effect at different velocities (0-M3), show and measure the vector force pressing perpendicularly inwards, optimize the rocket´s round end in order to reach highest vector force over velocity range.

milestone2: 50\$

show how this effect can be locally disturbed by what forces applied to the rounded region in order to let laminar flow stall. think of a foil with a rough surface (range 0-50µm of ie bubbles) that you glue to that region. Eliminate as much as possible the “sucking” effect. Show best roughness geometry.

milestone3: 50\$

create a thrust that propels the rocket to M2.5-3 within ideally 20m. show energy used on 0-100m, acceleration chart and thrust and drag and weight chart. Use any useful powder and metal, that s not important. What I need is a realistic thrust with a realistic cone geometry.

milestone4: 50\$

show how the thrust jet is influenced/squeezed by the orthogonal pressure vector caused by the coanda effect and released w/o coanda effect. If the rough stall producing foil would be just half around the rocket s end: what would be the turn rate? Optimize the fins to produce highest and lowest turn rate.

Milestones press

Design hpp press and fea and cfd and animation

Milestone5, 50\$

Design the water cylinder id66 od maybe 150mm, take a 200ton jack , piston with 20 steel rings from combustion engines, piston stroke500mm, and oil pump and push the piston to produce 6000bar, make fea and cfd and animation.

Milestone6, 50\$

Put water cylinder onto 4m tube with traveler (chamber divider with seals like o-rings), design c flanges and caps and 2 valves on each side, let water flow in when juice already fills the whole tube volume, press juice to 6000bar, make fea and cfd and animation.

Milestone7, 50\$

Put components around press like air pressure with 4 cylinders controlling the valves, design valves with sealing, choose cylinders: sucking juice and pressing into tube and the one pressing juice out with 10L of water, show interface to bottling station (no oxygen, all ss304 tubes), show system cleaning with water, make fea and cfd and animation.

Milestone8, 50\$

I send you links of all machines (washer, mincer, grinder, bottler, power units and cooler) and you integrate them into container. Make film of transparent container showing the whole system.

Milestone9, 50\$

2 more tube versions, all 4m, but id 150 and 300mm. make fea and cfd and animation.

Milestones printer

Milestone10, 50\$

Design a51 hp cartridge and attached container, with motored roller distributing each single height layer of metal up to 200°C, choose materials, do fea and cfd and animation (solidworks composer and material motion)

Milestone11, 50\$

Design carousel, comprised of ca 30 cartridges, with different speeds, verify/correct speeds, basis is 0.5m/s printing speed, show cfd of thermal behavior in cartridge and printed layers, optimize layer by printed mass and nano particle size.

Milestone12, 50\$

Design (preheating) hopper system for different materials (ceramics/different metals/plastics pa66/11/12), animation, cfd for all materials.

Milestone13, 50\$

Grow system to 10 cartridges per row, animation
