X-BAT Vertical Takeoff Propulsion System

2 posts · Jul 2026 – Aug 2026

What this trail covers

The X-BAT program continues to evolve its vertical takeoff and landing (VTOL) capabilities by integrating and re-engineering the Axisymmetric Vectoring Exhaust Nozzle (AVEN) technology. This post details the successful integration, actuation, and engine light-off testing of the AVEN with GE Aerospace's F110-GE-129E engine, adapting a 1990s F-16 thrust-vectoring nozzle for precise attitude control during hover and landing. Future iterations will focus on modern materials, guidance and control systems, and making the propulsion system faster, lighter, and more capable.

Aug 2026The Life of AVEN ® — How a 1990s F-16 Thrust-Vectoring Nozzle Became the Key to X-BAT’s Vertical TakeoffThis post details the successful integration, actuation, and engine light-off testing of the AVEN with GE Aerospace's F110-GE-129E engine. It describes the adaptation of a 1990s F-16 thrust-vectoring nozzle for precise attitude control during hover and landing, highlighting the challenges of rethinking actuation, interface with the engine, and communication with flight controls for VTOL operations. The post also outlines future work on reengineering the nozzle with modern materials, guidance and control systems, and production techniques.
Jul 2026Shield AI and GE Aerospace light off X-BAT engine, completing thrust vectoring nozzle integration and clearing path to vertical flightThis post details the successful integration, actuation, and engine light-off testing of the Axisymmetric Vectoring Exhaust Nozzle (AVEN) with GE Aerospace's F110-GE-129E engine for the X-BAT aircraft. It highlights the refurbishment and adaptation of 1990s thrust-vectoring hardware for the specific demands of vertical flight, including fast gimbaling for attitude control. The testing verified system performance and coordinated nozzle movement sequences, paving the way for flight tests.
