Electrical Vertical Takeoff And Landing and Unmanned Aerial Vehicals
EVTOLs and UAV's specialised Lubricant
Lubricants are essential for electric vertical takeoff and landing (eVTOL) aircraft, especially for high-speed components like gas turbine generator bearings, where they reduce friction and power loss. New bearing designs use centrifugal force and optimized spacer shapes to deliver minimal, optimal lubrication, reducing oil consumption by nearly 80%.
Why Lubricants Are Crucial for eVTOLs, eVTOLs rely on high-speed components, such as bearings in gas turbine generators, which require precise lubrication to operate efficiently and prevent failure. Proper lubrication minimizes friction, significantly reducing power loss in bearings and improving the overall energy efficiency of the aircraft. By reducing power consumption and minimizing the weight of lubrication components (like oil supply systems), advanced lubrication contributes to a longer flight range for eVTOLs.
Innovations in eVTOL Lubrication-
Minimal Lubrication:
Modern solutions focus on "minimal yet optimal" lubrication to reduce oil usage.
These new mechanisms can reduce the necessary lubricant supply by up to 80% and decrease power loss by nearly 30%. Lighter oil supply pumps and lubricant tanks are possible with these less demanding lubrication requirements, further improving vehicle efficiency.
