Electric Vertical Take-off and Landing (eVTOL) aircraft have the potential to revolutionize the field of aviation, offering a broad spectrum of applications ranging from urban air mobility to logistics and emergency medical services.
One of the most persistent and challenging issues in eVTOL design is meeting stringent weight requirements – hardly a new requirement in aircraft manufacturing. Engineers have been delving into innovative spatial and weight-saving solutions ever since the inception of aviation.
Many existing systems have exhibited the potential for seamless integration with emergent technologies. An example of this lies in aircraft sealing and material solutions, which facilitate the dependable and secure operation of crucial eVTOL systems:
- Propellers & Transmissions
- APU & Hybrid Power
- Flight Controls
- Environment Controls (ECS)
- Power Electronics
- Sensors
This article will delve into the essential role played by aircraft seals and materials in the rise of eVTOLs and their journey toward commercialization.

Jet Engine Polymer & Metal Seals: Key Precision Components for eVTOL Applications
Jet engine seals are a key element within contemporary aircraft design, offering an essential function. These seals ensure a secure and uniform enclosure that can endure elevated pressures and temperatures, thereby securing peak efficiency during the most extreme operational circumstances.
Omniseal® spring-energized seals and metal seals, in particular, have proven invaluable in jet and gas turbine engines, where conventional seals might fail due to the demanding environment.
The high adaptability achieved through customizing polymer jackets and spring materials or a coated metal ring, coupled with the flexibility to modify spring tension as needed, yields exceptional thermochemical harmony and rapid dynamics. These aspects are major criteria in the pursuit of expanding the performance capacities of eVTOL systems.
Turbofan Solutions: Adapting Sealing & Material Technology for eVTOLs
As the prevalence of eVTOL aircraft continues to rise, an increasing demand arises for inventive sealing solutions capable of meeting the distinctive requirements of this emerging technology.
Smart materials, advanced manufacturing techniques, and design principles are being employed to create aircraft seals that deliver reliable and efficient sealing performance in even the most challenging environments.
A notable instance of advanced material utilization in seal design involves the innovation of high-temperature plastics, exemplified by Omniseal Solutions’ Meldin® polyimides and Hycomp™ carbon composites.
These materials boast exceptional mechanical properties and can endure temperatures of up to 500 °C, rendering them optimal for application in high-temperature engine scenarios.
Naturally, eVTOLs do not have a conventional engine as their propulsion is generated electrically using a battery array. Although battery temperatures do not approach the extreme thermal loads of a jet engine, it is crucial to manage any thermal loads to ensure operational safety.
In the realm of seal design and refinement, sophisticated simulation tools such as Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) prove invaluable in modeling and simulating seal behavior across diverse operational conditions.
This empowers engineers to optimize seal shape, dimensions, and materials, thereby enhancing performance and diminishing weight and size. The advantages of advanced design and optimization software are multifaceted, particularly in the context of research and development (R&D) of novel mechanical systems.
The Future of Aircraft Seals in eVTOL Applications
Aircraft seals play a pivotal role in facilitating eVTOL applications and advancing urban mobility. As eVTOL technology progresses, the requirement for top-notch sealing solutions is set to surge, driving innovation in materials, design, and manufacturing methodologies.
Aircraft seals that are used in many different systems will prove essential for the successful commercialization of eVTOLs, providing the necessary reliability and efficiency required for their widespread adoption.
