Bringing together passionate women leaders and allies from Aerospace, Mechanical and related Engineering streams.
The aerospace industry is witnessing a groundbreaking innovation that could reshape the future of space exploration. Space Forge, a UK-based company, is making waves with its revolutionary heat shield known as "Pridwen," named after the legendary shield of King Arthur. Pridwen is set to unlock the potential of space resources for various research applications, including agriculture, alloy manufacturing, and pharmaceutical procedures.
What sets Pridwen apart is its design, inspired by origami principles. This relaunchable space shield is made of a high-temperature alloy fabric that can fold and unfold, minimizing its size when not in use. However, when deployed, it expands to create a substantial surface area, allowing it to effectively dissipate heat without compromising its structural integrity. This innovative design ensures Pridwen's reusability, making it a game-changer for space missions.
The key to Pridwen's effectiveness lies in its unique approach to heat dissipation. Unlike standard heat shields that gradually burn off pieces to remove heat, Pridwen relies on radiation. Its high-temperature alloy fabric boasts a sufficiently large surface area, allowing heat flux to spread evenly and gradually radiate away.
Moreover, Pridwen will serve as a safe means for the reentry of satellites. As a spacecraft begins its descent to Earth and encounters the atmosphere, its orbital velocity converts into high heat fluxes. Without proper protection, the spacecraft would simply burn up. Pridwen's shuttlecock-style shield is designed to slow down a satellite enough that it can safely land without the need for a parachute. Space Forge even envisions capturing satellites with a hover net, further expanding its capabilities.
The first Pridwen heat shield is slated to take flight aboard Space Forge's inaugural ForgeStar-1A mission later this year. This ambitious project has received support from the European Space Agency's General Support Technology Programme, which aims to ready promising technologies for space and commercial markets, as well as the UK Space Agency.
