Latest Patents

One of Lawson's latest patents is the Shell Tile Thermal Protection System. This reusable, externally applied thermal protection system utilizes a unique shell tile structure that effectively separates its primary functions as an insulator and load absorber. The tile consists of structurally strong upper and lower metallic shells manufactured from materials that meet the thermal and structural requirements for placement on spacecraft. The upper shell incorporates a lightweight, high-temperature package of insulation, while the lower shell features lightweight, low-temperature insulation. The assembly of the tile is facilitated by a self-locking mechanism, allowing for efficient installation on the spacecraft's structural skin.

Another significant patent by Lawson is the Modified Spiral Wound Retaining Ring. This invention features a spiral wound retaining ring with angled ends that are crimped at the same angle to maintain a constant thickness dimension. The design allows the ends to be positioned closer together while ensuring enough clearance for insertion and removal. By reducing the separation distance between the ends, the ring achieves greater strength due to the maximized double layer area.
