Aero Motive Slip Ring

The Aero Motive Slip Ring is a rotating conductive device designed specifically for the aviation industry. Its core function is to achieve stable transmission of power, signals, and data between rotating components (such as helicopter rotors, drone motors, and aviation radar antennas) and fixed components. Through the dynamic contact between the conductive ring and the electric brush, the Slip Ring solves the problems of electrical isolation and signal integrity in rotating connections, while also meeting the strict requirements of aircraft for weight, reliability, vibration resistance, and extreme environments.

2、 Key features

Ultra lightweight design

Features: Using titanium alloy (density 4.5 g/cm ³) and carbon fiber composite material, combined with topology optimization structure, achieving a weight reduction of 40%~60% compared to traditional metal Slip Rings.

Data: The weight of a certain type of drone slip ring is only 85 grams, supporting a torque transmission of 3 kg · m ² and a power density of 1.2 W/g, meeting the long endurance requirements of drones.

High speed and low inertia

Features: Ball bearings and aerodynamic design enable the slip ring to operate stably at 5000-20000 RPM, with a 25% reduction in rotational inertia compared to similar products.

Data: In helicopter rotor applications, torque fluctuations at 12000 RPM are less than 0.3 N · m, ensuring flight stability.

Extreme environmental tolerance

Features: With an IP68 protection level and a low-temperature resistant polyimide insulation layer, it can operate within a temperature range of -65 ℃ to+180 ℃ and has a vibration resistance of up to 15 g (20~2000 Hz).

Data: The slip ring of military helicopters has passed the MIL-STD-810G salt spray test (96 hours without corrosion) and is suitable for marine environments.

High density signal integration

Features: A single slip ring can integrate 200+channels and support synchronous transmission of power supply (0~1000 V~50 A), CAN bus, fiber optic (10 Gbps), and RF signals (Ku band).

Data: The slip ring of the early warning aircraft radar turntable integrates 48 power sources, 32 fiber optics, and 16 RF channels, increasing space utilization by 50%.

Ultra low contact resistance and high reliability

Features: Gold plated conductive ring (gold layer thickness ≥ 3 μ m) and carbon nanotube brush, contact resistance<5 m="">50000 hours.

Data: In the 1000 hour continuous flight test of the drone, the contact resistance change rate is less than 2%, reducing the risk of signal attenuation.
