CFD Visualization of an Aircraft Landing Gear Oleo Strut at Touchdown What looks like a simple landing gear component is actually a highly engineered energy-absorption system. During touchdown, the oleo strut converts the aircraft’s kinetic energy into controlled hydraulic energy through compression of the shock strut and metering of hydraulic fluid. 🔹 Before touchdown: The strut is fully or partially extended, with the hydraulic fluid at relatively low flow velocity. 🔹 Initial compression: As the wheels contact the runway, the piston begins moving upward into the cylinder, forcing hydraulic fluid through the metering orifice. 🔹 Peak compression: The metering geometry controls the hydraulic flow rate, producing resistance that absorbs a significant portion of the touchdown energy. 🔹 Rebound: After peak compression, the strut extends again while the rebound system controls the return movement and helps prevent excessive oscillation. The CFD visualization provides an excellent way to understand what is happening inside the oleo strut—something we cannot see during normal aircraft operation. From a maintenance perspective, understanding this flow behavior also helps explain why correct servicing, hydraulic fluid condition, nitrogen pressure, metering components, seals, and proper extension/compression checks are critical to landing-gear performance. Landing gear doesn’t simply “take the impact” it manages and dissipates energy through controlled hydraulic flow. {CFD stands for Computational Fluid Dynamics} #AircraftMaintenance #LandingGear #OleoStrut #CFD #ComputationalFluidDynamics
