Direction Controllers TRIZ Cases
- Distributed Munition Formation Control Without GPS
Shared datalink navigation lets each munition hold formation without GPS, avoiding central-node failure and reducing collision risk.
- Projectile Trajectory Estimation Using Reduced-Noise Position Smoothing
Smoothed in-flight position data and trajectory models cut GPS noise and bias, enabling earlier correction and more accurate impact prediction.
- Dynamic Autopilot Parameter Scheduling Across Flight Envelopes
On-board Mach and dynamic pressure sensing lets one guided rocket autopilot retune gains and filters for rotary and fixed wing launches.
- Multimode UAV Target Search and Homing for Collateral Avoidance
Dynamic switching between terminal homing and target search lets a UAV retarget or abort late-stage engagements to limit collateral damage.
- Wideband DF Aperture Layout for Low-Drag Wide-Frequency Coverage
Variable-size end-fire elements in one planar array replace multiple apertures, cutting drag and weight while preserving wideband direction finding.
- Interceptor Missile Selection Using Weather-Based Seeker Switching
Rainfall at the predicted intercept point guides selection of infrared or RF seeker missiles to cut cost without losing interception reliability.
- Projectile Guiding Fin Assembly With Adaptive Pitch Control
Spring-biased fins and spin braking adapt pitch to flight conditions, cutting energy loss while preserving projectile range and accuracy.
- Nested Gimbal Assembly With Concentric Sealing and Bearing Layout
A concentric motor, bearing, and ferrofluid seal layout cuts gimbal mounting space while preserving rotation, stiffness, and sealing integrity.
- Projectile Course Correction Using Sensor-Refined Trajectories
Onboard sensors and Monte Carlo trajectory refinement enable midcourse projectile correction when GPS is jammed or spoofed.
- Guided Munition Roll Orientation from Lateral Turn Estimation
Lateral acceleration, velocity, and turn-rate integration let guided munitions estimate roll orientation continuously during maneuvers.
- Missile Inertial Sensor Selection Across Flight Phases
Multiple inertial sensors are switched by flight phase to balance accuracy, range, cost, volume, and drift in missile navigation.
- Missile Salvo Trajectory Offsets for Simultaneous Target Arrival
Identical mission data and unique missile IDs create offset flight paths that avoid interference while preserving near-simultaneous target arrival.
