Hybrid Electric Engine

Product catalog summary

Introduction
Recent advancements in electrical motors, energy storage systems, and power electronics converters are making aircraft increasingly electrical. Hybrid technologies offer a viable option for greener air travel by converting multiple power sources to meet the aircraft's needs during flight. This highlights the importance of efficient power converters in hybrid engines.

Environment
The compact design and high efficiency of hybrid engines require a high-speed rotating shaft, with surface speeds exceeding 40 m/s (7900 ft/min), connecting the turbine and power converter. The generator shafts operate at variable speeds, necessitating a seal that allows minimal leakage across the speed range and lasts the engine's lifetime.

Challenge
The primary challenge is to ensure a long lifetime for the customized lip seal to minimize engine downtime. PTFE lip seals can operate dry in case of lubrication loss, enhancing system reliability. The compact design also simplifies the overall system and reduces weight.

Solution
Omniseal Solutions offers Omniseal® rotary lip seals that support compact design, high-speed sealing, and excellent durability. These polymer lip seals are made from a durable, long-wearing jacket material that provides excellent wear resistance, trusted by customers for many years.
