Vehicle Components Slip Ring

CENO produced kinds of slip ring include aerospace-grade vacuum conductive slip rings, device slip rings, and gas-liquid-electric combined slip rings. Specifically, these include slip rings for solar array drive mechanisms, space borne radar slip rings, control torque gyroscope slip rings, and slip rings for manned spaceflight extravehicular equipment. All must meet national military standards and aerospace-grade reliability requirements.

Core Application Scenarios

Satellites and Deep Space Exploration Slip rings for solar array drive mechanisms ensure the transmission of attitude control signals during 360° rotation of satellite panels, keeping the solar panels always aligned with the sun; slip rings for spaceborne microwave radiometers and scattering devices transmit high-frequency signals and data from remote sensing; slip rings for navigation enhancement antennas ensure stable transmission of satellite communication signals.

Manned Spaceflight and Space Stations Slip rings for space station robotic arms and extravehicular activity equipment support the transmission of power, video signals, and control commands during astronaut extravehicular activities; slip rings for control torque gyroscopes provide stable power transmission for precise attitude control of the space station.

Spacecraft Airborne radar and optoelectronic pod slip rings enable synchronous transmission of power, high-definition video, and radar signals from the rotating detection components of the spacecraft, in high-altitude and high-speed flight environments.

Aerospace slip rings represent the most technologically advanced and reliability-critical category of slip rings. Their core characteristics revolve around six key dimensions: vacuum compatibility, ultra-low temperature/high temperature tolerance, zero failure rate, lightweight design, long lifespan, and anti-interference capabilities.

Full adaptability to extreme environments Operating temperature range -55℃ to +120℃, suitable for space vacuum, microgravity, strong radiation, and alternating high and low temperature environments. Protection rating reaches IP65 or higher, with some models capable of withstanding low atmospheric pressure at altitudes above 21,336 meters and cosmic ray radiation. No volatiles or gas release occur, preventing contamination of optical and precision components in aerospace equipment.

Ultra-high reliability and zero-failure design As a critical component for single-point failure in satellites and space stations, aerospace slip rings adopt a precious metal bundle brush filament + composite gold-plated ring contact structure. The dynamic contact resistance fluctuation is ≤5mΩ, with no instantaneous interruption and no sparks. The single-channel rotation life is ≥100 million cycles. Some models have redundant designs (dual brush filament, dual-channel backup) to ensure more than 10 years of fault-free operation in orbit, eliminating the failure of aerospace missions due to slip ring failure.

Lightweight and Miniaturized The shell is made of lightweight, high-strength materials such as aerospace aluminum alloy and titanium alloy. The second-generation aerospace slip ring is 60% smaller and 50% lighter than the first generation, adapting to the stringent space and weight restrictions inside satellites and space stations. It integrates multiple channels for power, network signals, and fiber optic signals, achieving "small size, big function."

Multi-Signal Mixed Transmission and Interference Resistance Supports synchronous transmission of power, control signals, high-definition video, Ethernet, high-frequency radar signals, and fiber optic signals. The signal ring and power ring employ physical isolation and electromagnetic shielding design, adapting to the complex electromagnetic environment of aerospace and ensuring accurate transmission of remote sensing data, communication signals, and attitude control commands.

Special Function Integration Some aerospace slip rings integrate gas and liquid transfer functions, enabling gas and coolant transfer between rotating components, adapting to space station life support systems and satellite temperature control systems.

Military-grade manufacturing processes and certifications All aerospace slip rings must pass rigorous tests such as vacuum baking, high and low temperature cycling, vibration and shock, and electromagnetic compatibility (EMC) to meet aerospace-grade quality control systems. Some models must be certified by international aerospace agencies such as NASA and ESA to ensure absolute stability in the space environment.
