Combined Temperature Humidity Chamber for Aerospace Altitude Space Simulation

1. Product Name and Purpose

2. Product Features

• Robust and High-Pressure Chamber Structure
  • The chamber is constructed with a heavy-duty, aerospace-grade steel frame that provides unparalleled rigidity and strength. The frame is meticulously welded and treated to withstand the immense pressure differentials and mechanical stresses associated with altitude and space simulations. The chamber walls are made of specialized composite materials and advanced insulation, which minimize heat transfer and maintain precise temperature and humidity levels. The insulation is engineered to endure the rigors of extreme cold and rapid temperature changes, while also preventing any external factors from compromising the internal test environment. The chamber is equipped with a hermetic door seal and multiple pressure relief valves, ensuring a leak-free enclosure and safe operation under varying pressure conditions.
• Precision Temperature, Altitude, and Humidity Control System
  • The integrated control system is a marvel of technological sophistication. It can accurately replicate a wide range of temperatures, from -100°C in the frigid depths of space to +200°C in the heat of re-entry or engine operation. The altitude simulation capabilities extend from sea level to the vacuum of space, with the ability to precisely control pressure levels as low as 10^-6 torr. The humidity control range spans from near-zero dryness to saturated conditions, with an accuracy of ±2% RH. The system employs advanced refrigeration units, heating elements, vacuum pumps, and humidifiers/dehumidifiers, all coordinated by a sophisticated computerized control algorithm. Temperature, pressure, and humidity sensors are strategically placed throughout the chamber to provide real-time feedback, enabling the control system to make instantaneous and highly accurate adjustments.
• Vacuum and Space Simulation Capabilities
  • The chamber is equipped with a high-performance vacuum system that can create a near-space vacuum environment. It can evacuate the chamber to extremely low pressures, simulating the conditions of outer space. This allows for the testing of components and systems in a microgravity and vacuum environment, evaluating their behavior in the absence of atmospheric pressure and the presence of cosmic radiation. The chamber also features radiation simulation capabilities, using specialized light sources and shielding materials to replicate the effects of solar and cosmic radiation on aerospace materials and electronics.
• Advanced Data Acquisition and Monitoring System
  • A comprehensive data acquisition and monitoring system is an integral part of the chamber. It records and analyzes a vast array of parameters, including temperature profiles, pressure changes, humidity levels, and the performance of the test samples. The system can monitor electrical signals, mechanical vibrations, and other critical indicators of component health. The data is continuously logged and can be visualized in real-time on a user-friendly interface. Additionally, the system has the ability to generate detailed test reports, complete with graphs, charts, and statistical analysis, providing engineers with a wealth of information for performance evaluation and design optimization.
• Customizable Test Fixturing and Sample Handling
  • The chamber is designed with flexibility in mind, allowing for the accommodation of a wide variety of aerospace components and systems. It features customizable test fixturing and sample handling mechanisms that can be adjusted to fit the specific geometry and requirements of the test samples. Whether it's a small electronic circuit board, a large rocket engine component, or a complete satellite subsystem, the chamber can be configured to ensure proper positioning, connection, and exposure to the simulated environment. The interior surfaces are made of non-reactive and non-outgassing materials to prevent any contamination or interference with the test samples.
• Enhanced Safety and Emergency Systems
  • Safety is of utmost importance in aerospace testing. The chamber is equipped with a comprehensive suite of safety features, including emergency stop buttons located both inside and outside the chamber for immediate shutdown in case of any anomalies. It has overpressure protection systems, fire suppression systems, and leak detection sensors for refrigerants and other gases. The chamber is also designed to handle potential failures of the vacuum system or other critical components in a safe and controlled manner, with backup power supplies and redundant safety circuits to ensure the integrity of the testing process and the protection of personnel and equipment.

3. Specific Parameters

• Temperature Range and Rate of Change
  • The chamber can maintain a temperature range from -100°C to +200°C. The rate of temperature change can be adjusted up to 30°C per minute, allowing for rapid transitions between extreme cold and hot conditions. This is crucial for simulating the temperature differentials that occur during spaceflight, such as the rapid heating during re-entry or the extreme cold of deep space. For example, a spacecraft's heat shield must be able to withstand the intense heat of re-entry, and this chamber can accurately replicate those conditions to test its performance.
• Altitude Simulation Range and Pressure Accuracy
  • The altitude simulation range extends from sea level (101.3 kPa) to the vacuum of space (as low as 10^-6 torr). The pressure control accuracy is within ±0.1% of the set value. This precise altitude and pressure control is essential for testing the performance of aerospace components, such as aircraft engines, which experience significant pressure changes during flight. It also allows for the evaluation of the effects of low pressure on materials, electronics, and mechanical systems, such as the potential for outgassing or the degradation of seals and lubricants.
• Humidity Cycling Range and Rate
  • The humidity can be cycled from near-zero to saturated conditions, with a rate of change of up to 10% RH per minute. In aerospace applications, humidity can have a significant impact on the performance and reliability of components. For instance, high humidity can cause corrosion of metal parts or affect the performance of electronic circuits. The chamber's humidity control capabilities enable the testing of components under different moisture levels, simulating the diverse environments that aerospace assets may encounter, from humid tropical regions to the extremely dry conditions of space.
• Testing Volume and Payload Capacity
  • The chamber offers a customizable testing volume, with options ranging from 1 m³ to 20 m³. The payload capacity can be adjusted according to the size and weight of the test samples, with a maximum capacity of up to 5000 kg. This flexibility allows for the testing of a wide range of aerospace products, from small avionics components to large structural assemblies
