Integrated Fire Control for Fighters

Integrated Fire Control for Fighters is a key technology in future network centric warfare environment in air-to-air combat. Resource sharing of onboard active/passive sensors and weapons among fighter formation via local secured datalink will realize an air superiority to stealth and/or outnumbering enemy aircraft.

Weapons Bay System for Stealth Fighters

Weapons Bay System is one of the essential subsystems for stealth fighters. Housing stores within weapons bay have twofold benefit: reduced extra drag and smaller radar signature (by non-existence of any pylons and any external stores) . The system needs to work properly and launch weapons in a very short reaction time at high speed and high maneuver flight condition.

Intake Duct for Stealth Fighters

A Serpentine Intake Duct is considered as an effective measure to reduce radar reflection from an engine. Design technology with CFD analysis and boundary layer separation controls is investigated to solve air flow degradation caused by the serpentine. Thus both stealth and favorable aerodynamic characteristics are incorporated in the intake duct.

Research on lightweight airframe structure

In order to suppress weight increase, this research will investigate lightweight airframes using efficient and accurate structural analysis techniques, an integrated bonded structure with a greatly reduced number of fasteners and a high-performance heat-shield.

Electric Actuation Technology

Electric actuation system for flight control, landing gear retraction, steering and braking will replace present hydraulic system.

Airborne Sensor System for Ballistic Missile Warning

Airborne sensor system of IR sensor mounted on UAV is integrated for ballistic missile warning.

High-Power Slim Engine Technology

Thrust Vectoring Control Technology

3D thrust vectoring nozzle with all-around 20 degrees vectoring capability enables future fighter to achieve high maneuverability.

Technology of Direct Filament Winding Multi-segment Propellant Rocket Motor

Direct Filament Winding (DFW) Multi-segment Propellant Rocket Motor is investigated for the purpose of improving flight performance of guided missile and reducing production cost. Fundamental change of manufacturing method of rocket motor enables design flexibility of thrust pattern and large improvement in mass ratio.

Missile Guidance Technology in High Altitude & Speed Target

Missile guidance technology for high speed target in high altitude realizes Surface to Air Missile System to cope with low orbital theater (or tactical) ballistic missile and hypersonic velocity cruise missile in the future. Elements of this technology include Side Thruster against long periods of high pressure combustion, Thrust Vector Control (TVC) by jet tubs and high response Missile Guidance Algorithms.

Predictive Optimal Guidance and Control Technology

This technology reinforces missiles to cope with low RCS and high maneuverability target by application of model predictive control or optimal method to missile guidance.

Millimeter Wave Fire Control Radar Technology

Technology for millimeter wave fire control radar enables detection and tracking of seaborne, ground and aerial threats.

Future Fire Control Radar Technology

Technologies for future fire control radar enable detection and tracking of stealth Fighter / Bomber, high speed ASM and low altitude CM that are difficult to detect and track by conventional technologies.
