I. Core Challenges in High-Temperature Flow Field Measurement

In extreme condition testing for aero-engines and gas turbines, flow parameter measurement faces:
✅ Temperature Extremes: -20~1500°C coefficient drift from probe deformation
✅ Dynamic Interference: Transonic (0.1~2.0Ma) aerodynamic noise contaminating pressure signals
✅ Angular Sensitivity: Real-time 3D velocity vector resolution within ±30° yaw angle

II. Key Calibration Technologies (JJF 19 Standard Implementation)

1. Calibration System Configuration

Reference Wind Tunnel: Supersonic calibration tunnel with ≤0.5% turbulence (JJF 19 §4.1.3)

Temperature Simulation: Segmented thermal control system (-30~1500°C, ±2°C accuracy, GJB 4239 compliant)

Multi-Axis Positioning: 6-axis robotic arm (±0.1° angular accuracy)

2. High-Temperature Calibration Workflow

3. Performance Validation

III. Engineering Application Case

Turbofan Engine Test Bench (Inlet Flow Diagnostics)

Pain Point: 1200°C exhaust gas causing permanent deformation in 5-hole probes

Solution:
① Ceramic-Matrix Composite Probe (Ref: Product Doc §3.3)
② Coupled Thermal-Pressure Correction Algorithm

Result: Velocity field error reduced from 8.7% to ≤1.5%
