Rugged, Secure Data Storage for Propeller-Driven ISR Aircraft

Rugged, Secure Data Storage for Propeller-Driven ISR Aircraft

A major aerospace integrator was tasked with designing an intelligence, surveillance, and reconnaissance (ISR) system for a propeller-driven aircraft supporting long-duration missions. The platform needed a ruggedized network attached storage (NAS) solution that could withstand the shock and vibration of continuous flight, secure sensitive mission data, and integrate seamlessly with onboard ISR components. The system also needed to support high-capacity, removable media storage to securely transfer mission data and collected intelligence between the ground station and the aircraft.

The aircraft’s ISR system was built on an Ethernet backbone, requiring a NAS to manage simultaneous data exchange between sensors, a mission computer, and a data concentrator. Removable storage, with a minimum 4 TB capacity, was essential for transferring maps and mission plans from ground stations to the aircraft and retrieving sensor data post-mission. With data security as a top priority, the system required AES-256-bit encryption standards. Extreme durability was imperative to withstand the high levels of shock and vibration characteristic of propeller-driven aircraft. A ground station device was also needed to connect, decrypt, and download the removable memory onto a computer via USB.
