ABSTRACT
Supersonic parachutes are entities that decrease the speed of reentry rocket capsules from supersonic to subsonic speed. Deceleration is an important aspect of re-entry, whether on earth or on other planets. Capsules, with a weight of 2400 kg, reach a speed of more than Mach 2 with less than 62 miles (ca. 100 km) of deceleration length. This puts greater emphasis on the importance of a parachute system that effectively accomplishes a safe landing. Currently, parachutes use nylon and fiber material for landing, however, little research has been conducted on the effectiveness of these materials. Experimental factors like max load, material used, stability, and sustainability are all factors that scale the effectiveness of a parachute design. Through the use of CFD and FSI simulations, as well as physical data collected from experiments, an optimal parachute design will be tested.

  1. Good job on your poster presentation! I enjoyed seeing all your visuals and listening to your presentation. You did a great job explaining some terms before continuing the presentation to make sure your audience would understand what you are talking about throughout it. There is some interesting aspects to think about when it comes to parachutes and the materials used. I thought this was a very interesting topic and I see a lot of thinking and effort has gone into this presentation. The only thing I would recommend for future presentations is to make it so you are more explaining things rather than reading straight from a script. With that said, reading exactly quotes is a great way to refer back to a script but memorizing your script would make it sound like it is more explaining rather than reading if that makes sense. Overall you all did a great job explaining the designs and why they would work the best. Your point came across clearly and was concise. Thank you all I really enjoyed it!

  2. Hello Ojas and Yohannes,

    I found your presentation to be really interesting. One thing I did not know about it was the fact that the most simple designed parachute is still being used today. I never knew that when rocket capsules reenter into orbit that they could reach up to speeds of mach 2, to think that fabric like nylon is a major component in making the parachute to decelerate the rocket capsules is fascinating. One recommendation I would consider for your presentation would be to explain what you guys mean by the parachute design. Personally I thought about the ring cell design which is what you discussed in the video, but I also thought about the lines that are part of the parachute that connect to the rocket capsule as well. I am not sure if that is a whole different topic itself for the optimal design itself for the parachute but it would be interesting as I assume that it takes on a great amount of force once it is deployed and slows down the rocket capsule during reentry. Thats my only feed back for your presentation as it was really good and easy to under stand as you broke down what words meant at the beginning of the presentation.

  3. Hi Ojas and Yohannes,

    Great job on your poster presentation! I really enjoyed that you explained the material and terms before going into depth. I also thought it was interesting that parachutes have not really been changed or developed differently after all of this time. You guys are doing some really interesting and useful work. The only thing that I would recommend for future poster presentations have the definitions of the terms described on the actual poster for reference. Other than that I really enjoyed your presentation, keep up the good work!
