New Unmanned Air System Tested on USS Coronado

By Gabrielle Gibert

(WASHINGTON) -- Researchers from the U.S. Naval Research Laboratory (NRL) successfully completed testing their Nomad flight vehicle off of USS Coronado (LCS 4) in August. This test demonstrated the Nomad’s upgraded launch and control capabilities as well as a new recovery capability by launching multiple vehicles in quick succession, conducting formation flying operations, and recovering all vehicles sequentially onboard the USS Coronado.

“Nomad, is a low-cost rotary wing vehicle in which researchers can test remote control, autonomous flight control, station keeping and safe coordinated flight supporting any number of possible future payloads,” says co-principal investigator Steve Tayman, senior aerospace engineer with NRL’s Vehicle Research Section (VRS). “The unique form factor provides compact, light-weight storage in an integrated launch tube, and allows for storage in a ready-to-use condition for quick reaction deployment.”

The Nomad is a highly affordable expendable design, allowing for execution of its mission without concerns for returning to the ship. This new upgrade retains the original affordable expendable design, but now has a recovery feature that allows operators to retrieve and reuse the Nomad vehicles multiple times in support of development, testing, training, and potentially future operational missions.

The Nomad’s launching system originally supported singular, non-pyrotechnic launches utilizing a CO2 ejection system from the launch and storage tube; a safer alternative to pyrotechnic launching systems according to Tayman.

The system now has multi-launch capability, deploying multiple Nomads in quick succession instead of singularly, while retaining the system’s safe CO2 ejection system design. Tayman states that this creates an equally safe launching mechanism that can support a higher quantity of Nomads.

The Nomad test on Coronado marks the first time this multi-launch and retrieval technology has been tested on a U. S. Navy ship. “We’re excited to demonstrate this technology utilizing forward deployed fleet personnel and assets, testing one of our newest technologies on the Navy’s newest class of ships,” says co-principal investigator Aaron Kahn, a senior Guidance, Navigation, and Control researcher also with the VRS.

“During this test we were able to show multiple Nomads can safely operate in the same airspace and fly in a coordinated fashion. The ability to retrieve Nomads back onboard the ship opens up future opportunities for testing and fleet training with more expensive payloads – an aspect of affordability that can easily be overlooked” says Kahn.

Integrating Nomad onto Coronado speaks to the future of unmanned air systems and their contribution to the needs of the Navy. “Nomad will provide a unique opportunity to research and develop innovative ways to use the capabilities of an unmanned platform married with a variety of cutting edge payloads to address the unique Navy needs of today and tomorrow,” says Kahn.

The Nomad project is funded by the Office of Naval Research.
