EvTol Gaskets

The world of electric vertical takeoff and landing (eVTOL) aircraft is fast changing, and engineers are encountering complicated difficulties in the development phase. One of the most significant concerns is ensuring that these aircrafts have dependable Electromagnetic Interference (EMI) shielding Environmental Sealing, and Thermal Incident protection.

Since the development of eVTOL overlaps with the development of 5G, these air mobility vehicles are likely to employ densely packed circuits that create a lot of heat and are prone to cross-talk. That’s where EMI Seals & Gaskets Ltd comes in, offering high-quality EMI shielding gaskets, anti-vibration seals, window and door seals, hatch seals, and Battery compartment seals. Our products are made with aircraft-grade materials and designed to withstand the rigorous demands of eVTOL aircraft.

Shielding against Electromagnetic Interference (EMI) and Environmental Sealing

Electric vertical takeoff and landing (eVTOL) vehicles rely on complex electronics and tightly packed circuits to perform. However, these circuits emit electrical noise and are vulnerable to cross-talk, which can result in electromagnetic interference (EMI). EMI can interfere with communications between aircraft and control centres, potentially resulting in safety hazards. At EMI Seals & Gaskets Ltd, we provide eVTOL engineers with the trustworthy materials they need to guarantee smooth and safe operations by combining shielding with heat resistance and environmental sealing.

eVTOL planes fly in a variety of situations, from high altitudes to harsh weather. As a result, they need reliable environmental sealing against water, rain, sunlight, and ozone. EMI Seals & Gaskets Ltd provides a variety of aircraft-grade materials that provide dependable environmental sealing, ensuring your aircraft runs smoothly and safely in any circumstance.

Anti-Vibration Seals

Although the brushless DC motors that are used with eVTOL aircraft do not generate significant amounts of EMI, these motors are not altogether free from electronic noise. Soundproofing is critical for eVTOL pilots, who are more sensitive to noise, vibration, and harshness (NVH) from outside sources. Furthermore, eVTOL vehicles are expected to travel shorter distances than commercial aircraft and to do several takeoffs and landings each day. Interconnects must be dependable and able to endure vibration and shock caused by more frequent landings and takeoffs.

EMI Seals & Gaskets Ltd offers a variety of aircraft-grade materials with a variety of characteristics such as anti-vibration mounts, which aid in the reduction of NVH and BSR. Our anti-vibration seals absorb vibrations and stress, keeping them from entering the cabin and functioning as insulation between various components.

Window and Door Seals

When it comes to designing seals for doors and windows in eVTOLs, altitude is a crucial consideration. As the aircraft ascends, the air pressure decreases, which can lead to air leakage around seals and potentially compromise the safety and comfort of passengers. At high altitudes, the air is thinner, and there is less oxygen to fuel a fire. However, the enclosed space inside an eVTOL can trap smoke and toxic fumes, making it a potentially deadly environment for passengers and crew. To eliminate the risk of passive fire and smoke inhalation, it’s essential to use fire-resistant materials in the door and window seals of eVTOLs.

That’s why it’s important to choose seals made of high-quality materials that can withstand the extreme conditions of high-altitude flight. At EMI Seals & Gaskets Ltd, we offer fire-resistant materials that can withstand pressure and temperature changes at high altitudes, ensuring the safety and comfort of your passengers. EMI Seals and Gasket Ltd’s Firefill is an intumescent material that expands when exposed to high temperatures, creating a barrier that helps prevent the spread of fire and smoke. When exposed to high temperatures, the material expands to several times its original size, sealing off the opening and preventing the spread of fire and smoke.

Battery Compartment and Hatch Seals 

At EMI Seals & Gaskets Ltd, we have developed a unique range of products specifically for Battery Enclosure or Compartment safety. We have developed an integrated product that offers very high IP sealing, in conjunction with very High Shielding but that also incorporates a passive fire barrier that can protect occupants and critical equipment from potential harm should there be a Thermal Incident.

The passive fire products we have developed are Fireflex and Firefill. These materials are highly resistant to fire, heat, smoke,and corrosive substances, ensuring the safety and reliability of your aircraft. Fireflex is a special material that is highly resistant to fire, smoke and heat. This material is a flexible smoke and fire barrier that can withstand 1000+ °C and can be used to line compartments, walls, floors and ceilings to offer a firewall. Fireflex is a passive material that can be incorporated into seals to offer a combination IP/EMC/Fire/smoke barrier seal or it can be used on its own to create a fire/smoke barrier if there is an incident in a critical area.

In eVTOL aircraft, hatch seals are used to create a tight seal between the hatch cover and the aircraft body, protecting the cargo or passengers inside from water, dust, and other debris. Engine compartment seals, on the other hand, prevent engine fluids from leaking and keep the engine compartment clean and free of debris. Both hatch seals and engine compartment seals must withstand high temperatures, vibrations, and other stresses associated with electric motors and high-speed flight.
