Payload unit

The payload unit (PLU) is an individual engineering assembly unit. The PLU comprises a payload fairing, spacecraft, SC adapter (or dispenser in the case of a cluster mission), and a payload adapter.

Components and Assembly

The payload unit is an individual engineering assembly unit. The PLU comprises a payload fairing, spacecraft, SC adapter (or dispenser in case of a cluster mission), and a payload adapter. All the PLU sections meet the cleanliness requirements and are suited for use in the environment defined as ISO 14644-1 Class 8. To maintain required temperature and humidity for SC between the PLU integration and the launch, a ground-based system supplies the air with controlled temperature, humidity, and cleanliness inside the PLU.

payload adapter height: 725 MM

upper ring diameter: 2660 MM
