About
The Payload Adapter Plate is used on the payload end of a CubeSat Kit™ structure. Precision constructed from Al 5052-H32 and plated according to the CubeSat Design Specification (CDS), each Payload Adapter Plate is secured to the Chassis Walls via four M3 flathead stainless-steel screws.
The Payload Adapter Plate serves as a bulkhead between the sheetmetal Chassis Walls and an external payload (typically machined from aluminum) that mounts to the plate via an M3 bolt square pattern. By selecting an appropriately sized Chassis Walls, users can build a hybrid sheetmetal + machined-aluminum CubeSat structure, or attach additional “solid” structural elements to a CubeSat Kit™ structure.
The Payload Adapter Plate is often paired with a Payload Cover Plate Assembly, with a machined aluminum user payload located between the two. As Flight Hardware, it is Flight Qualified and Space Proven.
