Plumis; CubeSat Design Challenge Submission by Connor Tinker · 模型 198085
Plumis, this CubeSat challenge entry, was designed by a high school Junior named Connor Tinker. Because of the GrabCAD challenge regulations, it is being submitted by the student's father, Richard Tinker. -Lightest CubeSat ever recorded -Utilizes DMLS or SLS manufacturing processes, and 3 different metal based material options (Including two never before used on CubeSats) -Modular design with various adjustable mounting holes -Over 900,000 mm^3 of space for test equipment -Can withstand common 60G's created by rocket motor vibe, and up to 150G's with negligible deformations. -Simple two part body utilizing stock parts, and low cost materials to improve value Plumis is the result of a month of research, and design, put through a collaboration between mechanical and aerospace engineers from The Johns Hopkins University Applied Physics Laboratory, and Google, mentoring a high school student pursuing mechanical engineering. The name Plumis comes from the latin word for feathers, and reflects this designs groundbreaking innovations. Plumis is designed to be the worlds lightest CubeSat structure ever made, with a frame weighing in at only 84g. With over 900,000 milimeters cubed of storage space, this design allows for researchers to safely send large heavy test equipment into the very depths of space at a low cost. The second design objective of Plumis was to make it robust, and environmentally flexible. From the mass equivalence launch load curve, we determined that the largest forces a CubeSat would undergo (due to rocket motor vibe) are 60G's. According to design simulations, Plumis can withstand these forces with negligible deflections and only 4.9 MPa of Von Mises Stress at certain frame locations. As CubeSats become more common, and less expensive, more varieties of research will be performed using these structures. Currently, CubeSats are launched no further than L2 orbit (Lagrangian orbit), for data transfer technology used on research budgets cannot send information across any longer of a range. But, as data technology becomes innovated (with it will, exponentially), researchers will want to send their satellites deeper into space, to take new, groundbreaking measurements. Space itself is only 3 Kelvin, or -270 degrees Celsius. Radiation and planetary albedo can make testing environments a cool 25 Kelvin, or -250 degrees Celsius. This means that in order to innovate, and change the way we design and manufacture CubeSat structures, w...
