Join us for an on-demand VELOVirtual webinar, as we explore how advancements in design software from nTopology, combined with the improvements in manufacturing from Velo3D, helped Aerojet Rocketdyne set a new benchmark for their deep-space combustion design.

NASA’s planned return to the Moon for long-term exploration and utilization is currently underway and driving a new era in commercial spaceflight. But a lot has changed since humanity last visited the moon fifty years ago on Apollo 17.

Today, new technologies exist to drive down propulsion cost, speed up schedules, and improve performance. The availability of powerful computers to assist with design and simulation and advanced additive manufacturing to enable new part geometries offers engineers a chance to innovate without compromise and propel humanity’s ambitions for space exploration.

The company’s quad-directional propulsion is an amazing innovation in design, affordability, and performance. The technology enables the spacecraft/lander to efficiently accelerate in multiple directions which in turn makes maneuvering possible in the moon’s airless exosphere.

We will discuss:

  • The role of Laser Powder Bed Fusion (LPBF) to manufacture a near net shape lightweight and efficient “quad” reaction control system
  • Provide a recap of 2019 development efforts
  • Examine multidisciplinary optimization in 2020-2021, including:
    • Mass optimization using nTopology Software
    • Manufacturing improvements using Velo3D’s end-to-end manufacturing solution
