I am an undergraduate in aerospace engineering at a university in South Korea. Recently, I started to study rockets, and I think my passion for them has increased through this video. Now we're building a rudimentary solid-fuel rocket, but we've been able to set our sights on developing a hybrid rocket. Thank you for creating this video.

Nothing feels better than working with other people who share your same passions, interests, and drive for success. I am an engineer and have worked with wannabe engineers who just want a degree to collect a paycheck( they will fail and wash out), lazy people, you name it. But when you finally work with those true engineers and scientists, its truly an intellectual and emotional experience.

[@mplaw77]

I built a liquid fuel rocket in high school using concentrated nitric acid and 80/20 blend of turpentine/Furfuryl alcohol the engine was pressure feed using dry ice to supply pressure. The engine was made of stainless steel with a stainless steel insert nozzle. The injectors were parallel cylinders with semi-circular spray pattern opposing each other. The get the proper flow and ratio ... the number of injector holes was determined experimentally using water. The fuel and oxidizer tanks were made of aluminum tubing 3 inches OD, 1/8 wall thickness . The engine was static fired twice and the third time flown, the burn time was 7 seconds. The parachute failed but the rocket performed well. The combustion chamber cooling was supplied by the fuel with a simple tubular steel jacket. The nozzle was not cooled but as it was machined from stainless steel bar stock made for a heat sink. I made the drawings and had a little help with the calculations from and rocket engineer working for Bell Aerospace (a neighbor) the construction was done by a friend as a shop project in the high school shop, (some instructor) time went into the making. Our materials were more challenging than the soft band iron projects other kids worked with .... we also had to so some wet sand casting of aluminium. Age 15 years old the year before the shop project was a large solid propellant rocket. That too had a parachute failure and ended up in Lake Ontario and was flown once, the parachute ejection tested once at the same time a burst plug was tested on the motor. The rocket was constructed of low carbon steel ....SAE 1020, we were serious rocket boys and we lucky not to have blown ourselves up. Our neighbors were glad to see us graduate and go on to University, we rattled the windows in the neighborhood a few times.

[@donjones4719]

This video is so well done on so many levels. It's good to see someone combine knowledge with wisdom about knowledge, and aware they are doing it. But... MIT students? Or are you guys all in film school, pretending to be rocket scientists? There's not a nerd in sight! :-) Seriously, well done. Of course, there's always one quibble. You showed us an experiment, but didn't give us the full results. Yes, it fired, but did it reach its design performance? A minute of him looking at his data would have been great, make this self-contained. Although I will look here for the forthcoming video/link by him. Sam, congrats on an awesome piece of work, and good luck on your SpaceX internships. Am a huge fan of space rocketry since watching the Mercury/Gemini/Apollo as a kid. Tremendously excited by what SpaceX is doing.

[@samaustin7952]

Thanks Don! The engine was designed for 1,500 lbf thrust but actually hit around 1,300 lbf because of issues calibrating the helium gas regulators prior to the test. Because the regulators weren't set quite correctly, the propellant tank pressure was slightly lower than required and thus the chamber pressure and thrust were lower than expected.

[@henkdemetsenaere1374]

Sam Austin this is a late reply but wouldn’t the engine have more power if you give the nozzle a better shape.

[@vikhnesh313]

You should upload more videos like this. This is god dam inspiring..

[@satuor1076]

many people might not get it. there is so much difference when an experienced man creates a rocket and a student. a student is happier when he success because he is still a newbie. when he realize that he succeed then you have to know all of that complicated measurements were right.

[@mplaw77]

In high school, I teamed up with a buddy taking metal shop. We built a bipropellant hypergolic rocket and flew our rocket. Our parachute failed, and the rocket is now at the bottom of Lake Ontario, NY near Sodus Point. I did the design work and got some pointers from a young Aerospace engineer working for Bell Aerospace on NASA's Agena rocket during project Gemini. He helped me calculate the stress and strain for our propellant tanks and airframe. Using dry ice sublimation, our rocket pressure-fed the propellants to push red-fuming nitric acid and furfuryl alcohol into a stainless steel combustion chamber. The valves to start the flow were our own design; we used black powder to open the values when commanded by an electrical squib. The tanks were made of aluminum, the plumbing was made of stainless steel, and the nose cone was fashioned by my friend on a wood lathe. We static-fired the engine once, and many oractices runs with water. Our burn time was 7 seconds and the maximum thrust was at time zero and fell as the delivered pressure fell. Based on time of flight it reached approximately 2000 feet altitude. We had a better record that NASA! All their rockets blew-up on their frist flight test. My friend went to junior college and worked as a shift worked for Chevy, later got a degree and went to Law School. I went to school in the midwest known for Aerospace engineering, but working full time made long labs impossible so I switched to Physics and Chemistry and worked in Chemical research after starting in a control lab on rotating shifts. I did not have the grades in HS for MIT or high enough test scores to offset my GPA. MIT was top teer, the top 1% students. My buddy and I were maybe in the top third in a competitive high school. My only school talent was the sciences, and I was not handy working a lathe like my buddy, for him, science beyond auto mechanics was not really his thing.

[@taylorIndependenceHall]

This is inspiring. I am a junior in college and have been getting a little burnt out. Watching This video made me realize what i'm missing and that outside of school passion. Thank you so much and i look forward to your success at MIT.

[@akshatmishra4504]

literally my eyes filled with i thing a combination of salt and water when he said that what was the worth of spending this much resource on a 3 second thrust. I felt that. I too made a rocket thruster. Nobody supported me, so i took challenge alone and made it through. But i had failures and am happy for that because life of an engineer is full of failures. As 16 year old in country like India you dont get much freedom to do whatever you want. But am happy to see the video. Lets see will be applying this year. Am excited for more goosebumps by performing my own rocketry designs.
