GA-ASI Completes Key Wind Tunnel Test On Sea Avenger UAS

Test Results Validate Performance Of Aircraft for U.S. Navy UCLASS Program

Key wind tunnel test on a model of the Sea Avenger UAS have been completed by General Atomics Aeronautical Systems, Inc. (GA ASI), the company said Tuesday. Sea Avenger supports the Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) program by providing a long-endurance, survivable, carrier-based UAS for the U.S. Navy.

The wind tunnel test validated the low-speed characteristics of a new wing, resulting in higher endurance and lower approach speeds.  The new wing is also designed to increase aircraft dash speeds, decreasing the time to respond to potential threats. "GA-ASI is committed to providing the Navy with swift delivery of a robust and versatile aircraft carrier-based UAS that meets or exceeds known requirements, provides measurable manpower savings, and assures best value," said Frank W. Pace, president, Aircraft Systems Group, General Atomics Aeronautical Systems, Inc. "Reducing risk is a key component of this process, and our company has repeatedly designed and delivered low-cost, high-quality UAS, in part, because of our recurring commitment to invest in early development, as evidenced by this recent wind tunnel test."

The 90-hour, eight-day test was conducted at the San Diego Air & Space Technology Center. The goal of the test, which was completed ahead of schedule, was to validate the low-speed characteristics of an updated wing in the approach, launch, and cruise configurations.  The advanced design utilizes proprietary wing technology that enables high-speed flight, while also supporting excellent low-speed handling qualities desired for aircraft carrier landings.

The testing enabled GA-ASI to evaluate a specific set of configuration changes both quickly and economically.  Wind tunnel testing also helps reduce program risk by providing empirical data to complement computational analyses.  In addition, it provides the opportunity to correlate key performance data to analytical tools, such as computational fluid dynamics, and to validate various analytical methods.

Designed for fully autonomous launch and recovery from both USS Nimitz and USS Ford class carriers, Sea Avenger provides unmanned, autonomous, and long-endurance Intelligence, Surveillance, and Reconnaissance (ISR) capabilities responsive to the multi-mission requirements of carrier-based aircraft.  The aircraft will provide for planning, control, tasking, collection, processing, analysis, and dissemination of actionable information in support of Navy missions.
