12 ft D-Shaped Thermal Vacuum Chamber for Spacecraft Testing

Spacecraft and satellite manufacturers rely on thermal vacuum testing systems to validate performance before launch. A customer developing large spaceflight hardware needed a custom thermal vacuum chamber that could handle complex payloads while improving accessibility and test efficiency. Traditional cylindrical chambers limited usable space and made integration more difficult.

To address these challenges, Dynavac developed a 12 ft D-shaped thermal vacuum chamber that maximizes usable volume within a compact footprint. The system features walk-in access, a rail-mounted sliding platen for efficient payload handling, and dual independent thermal zones for precise control. Integrated controls and a LabVIEW-based HMI ensure repeatable, high-performance thermal vacuum testing for spacecraft and satellite applications.

12 ft D-Shaped Thermal Vacuum Chamber for Spacecraft Testing

This video introduces a 12 ft D-shaped thermal vacuum chamber designed for space simulation and spacecraft testing. The system recreates the extreme vacuum and thermal conditions experienced in orbit, enabling aerospace organizations to validate mission-critical hardware before launch.

Engineered for large spacecraft, the chamber features a flat-surface D-shaped design that maximizes usable internal volume while simplifying payload integration and handling. The system achieves vacuum levels down to 1 × 10⁻⁶ Torr and thermally cycles from −180°C to +150°C using Dynavac gaseous nitrogen thermal conditioning units.
