Spaceship Launch - SpaceX - NASA Astronauts

On May 30th, 2020 SpaceX launched NASA astronauts Robert Behnken and Doug Hurley aboard the SpaceX Crew Dragon capsule … This launch marked the return of a human launch capability on a United States rocket and capsule. I want to thank you personally for your dedication and hard work during the last several years to make this accomplishment possible.

Common aerospace seal types, unrelenting performance requirements.

Seals in critical aerospace need to meet performance conditions that can change dramatically between takeoff or launch, high altitude or orbit, and return to landing.  They need to function at ambient temperature, elevated and subzero temperatures often within the course of minutes or hours.  Specialty material formulations and profiles are developed for fuel and coolant management, jet and rocket fuels, landing gear and flight control actuation hydraulics.  Seal types range from o-rings through fluid power seals, cassette seals, boots, bellows, and plate seals, and rubber/metal bonded configurations.

Choosing the very best seal for the job

Aerospace engineers have long understood the criticality of seals.  Program development periods are among the longest due to extensive qualifications and subsystems testing requirements.  Our technical team at Darcoid is driven to help you develop the best possible seal for your unique application.  It is not unusual for new seal material formulations to come on line during program development, or conversely elastomer formulations may be retired by seal OEMs before a program launches.  We have close technical relationships and stay up to date with latest material developments or retirements.  Engage with a Darcoid applications engineer - we’ll share the latest news so you can keep your legacy specs up-do-date.

Seal Design

Identifying and controlling “Performance Creep” for future builds.

A critical part of your program’s success is making sure the seal that gets assembled in your product 4 or 5 years from now performs the same as the seal you qualify for production release.  Aerospace seal specs are among the most precise of all industries, but small omissions or assumptions in your control specs can still create major headaches in the future.  Flow down requirements only work if they are comprehensively flowed down your supply chain.  We can help audit your specs from an outsider’s perspective and show where you may be risk-exposed or conversely, over spec’d.  Darcoid Applications Engineers will share some of the additional Seal Performance Creep mitigation steps we’ve developed so you can rest easy and focus on developing your next great thing! 

Advanced Specification Support
