Why the U.S. Military Trusts Calspan for Captive Trajectory System Testing

Introduction

In the aerospace and defense industries, precision and reliability are non-negotiable. One of the critical testing methodologies used to ensure the accuracy of store separation (such as missiles, bombs, or pods from aircraft) is Captive Trajectory System (CTS) Testing. This advanced testing technique plays a vital role in validating the safe and effective release of stores under various flight conditions.

Calspan, a leader in aerospace testing and research, has been at the forefront of Captive Trajectory System Testing, providing cutting-edge solutions to military and commercial aviation sectors. This article explores the importance of CTS testing, its applications, and how Calspan contributes to advancing this technology.

What is Captive Trajectory System Testing?

Captive Trajectory System Testing is a wind tunnel testing method used to simulate and analyze the separation of stores (e.g., weapons, fuel tanks, or payloads) from an aircraft. The system measures aerodynamic forces and moments acting on the store during release, ensuring that it follows a safe and predictable trajectory without colliding with the aircraft.

Key Components of CTS Testing:

1. Wind Tunnel Testing – Conducted in controlled environments to replicate real-flight conditions.
2. Force and Moment Measurement – Sensors capture data on aerodynamic forces affecting the store.
3. Trajectory Simulation – Predicts the store’s path post-release using computational models.
4. Modeling & Validation – Ensures accuracy through repeated testing and adjustments.

Why is Captive Trajectory System Testing Important?

The primary goal of Captive Trajectory System Testing is to enhance mission safety and effectiveness. Here’s why it’s indispensable:

Ensures Safe Store Separation

• Prevents collisions between released stores and the aircraft.
• Validates ejection mechanisms under different flight conditions.

Optimizes Weapon Performance

• Ensures weapons follow intended trajectories for maximum accuracy.
• Reduces risks of misfires or deviations.

Reduces Development Costs

• Identifies potential issues early, avoiding costly in-flight failures.
• Minimizes the need for live flight tests.

Supports Regulatory Compliance

• Meets military and aviation safety standards.
• Provides verifiable data for certification processes.
