Silicon Architecture Driving Unprecedented Agility
The missile’s flight computer is built on a radiation‑hardened 28 nm ASIC that integrates a multi‑core DSP fabric with on‑chip FPGA re‑configurable logic. This hybrid allows real‑time execution of high‑G maneuver algorithms while maintaining deterministic latency under 5 µs per control loop.
MEMS‑Based Inertial Navigation Core
At the heart of the guidance suite lies a tri‑axis MEMS gyroscope and accelerometer array fabricated using silicon‑on‑insulator (SOI) technology. The sensor fusion engine runs a Kalman filter on the ASIC, delivering sub‑meter positional accuracy even in GPS‑denied environments.
Thrust Vector Control & Aerodynamic Surfaces
The XKJ301‑1 turbofan is coupled with an electro‑hydraulic thrust‑vector nozzle that pivots ±15° in pitch and yaw, commanded by the ASIC at 10 kHz update rates. Pop‑out wings lock via shape‑memory alloy actuators, providing a rigid 3 m span for lift‑to‑drag optimization.
Stealth and Radar Cross‑Section Reduction
- Angled composite panels with RCS < 0.01 m²
- Radar‑absorbent coating using carbon‑nanotube infused polymer
- Internal routing of RF antennas to minimize external protrusions
Terminal Phase Maneuvers
During the final 30 km of flight, the missile executes programmed barrel‑rolls and high‑G weaving patterns. The control law leverages the ASIC’s FPGA to generate pulse‑width modulated commands to the thrust vector and control surfaces, achieving lateral accelerations up to 15 g without compromising structural integrity.
Multi‑Mode Homing Suite
Simultaneous imaging infrared (IIR) and radio‑frequency (RF) seekers are processed on a dual‑core AI accelerator, enabling target discrimination against decoys and clutter at ranges beyond 50 km.
