挑战
Develop and optimize telescope stabilization, a tracking camera, and interface systems for the Stratospheric Observatory for Infrared Astronomy (SOFIA), a flying observatory. The challenge was to create a system that could operate effectively in the stratosphere, where conditions are harsh and the need for precise stabilization is critical. The team needed to standardize on a common 3D design platform to facilitate collaboration and development, especially given the involvement of multiple disciplines and international partners.
关于客户
The Stratospheric Observatory for Infrared Astronomy (SOFIA) is a unique flying observatory developed through a partnership between the German Aerospace Centre (DLR) and NASA. It is a refurbished Boeing 747 SP aircraft equipped with a 2.7-meter infrared telescope, allowing scientists to observe the infrared spectrum of light from the stratosphere. The German SOFIA Institute (DSI) at the University of Stuttgart and the Universities Space Research Association (USRA) in the United States coordinate its scientific operations. The project involves a consortium of German industry for the telescope's design and manufacturing, while NASA handles aircraft modifications, telescope installation, and operations. SOFIA's key advantage is its ability to position itself at precise locations to observe rare celestial events, providing a unique platform for astronomical research.
解决方案
The SOFIA development team utilized SOLIDWORKS Research Edition software as the primary platform for designing and optimizing the telescope stabilization, tracking camera, and interface systems. The software's ease of use and integrated simulation tools made it an ideal choice for the project. The team used SOLIDWORKS modeling software to design various assemblies and components required to stabilize the telescope and tracking cameras during flight. They also leveraged SOLIDWORKS Simulation tools to validate and optimize design performance in the challenging operating environment of a moving aircraft in the stratosphere. The advanced design visualization capabilities in SOLIDWORKS facilitated communication across different disciplines involved in the project, including electronics, software, and optics development.
运营影响
  • Supported important achievements in astronomical discovery, such as the occultation of Pluto and the discovery of new molecules in the interstellar medium.
  • Optimized the interface between the telescope and tracking cameras, ensuring precise stabilization and tracking during flight.
  • Decreased the weight of parts by using SOLIDWORKS Simulation tools, which helped reduce material and weight on components with low operating stress.
数量效益
  • Reduced material and weight on components, leading to a lighter overall system.
  • Strengthened parts where the stress is high, ensuring durability and reliability in the stratosphere.
