Welcome To The Metallic Hi Temperature Seal Systems
The Metallic Hi Temperature Seal System (US patent issued) was designed by our team after several conversations with colleagues in the airline industry. These professionals repeatedly mentioned the issues the airframe companies were having when applying elastomeric seals to high temperature areas, particularly in the inner fixed structure of the nacelle. It quickly became apparent to us that the elastomeric seals would never work in a high temperature environment.
As a result, we took on this challenge to design a replacement system for the elastomers where temperatures would typically exceed 500'F. The product of our efforts culminated in using "Old School" technology, which has already proven to work in currently applied "hot section" areas of existing jet engines. This legacy technology revolves around the use of the spring or "turkey feather" seal design using INCONEL alloy 718 material.
Our High Temperature Seal System specifically addresses the issues facing the elastomeric industry, and provides the solution to those problems not currently resolved by the elastomeric seal makers. Our patented design is unique, but quite simple. In fact, we have successfully fire tested our design, and have found that our seal – even after being exposed to temperatures greater than 2400' F – showed no flame leakage and retained its original shape with NO evidence of material deformation or degradation.
Furthermore, we have a retro-fit solution for use in existing high temprerature elastomeric seal applications. Our seals will directly attach to the existing retainer, and will be a direct replacement alternative to using an replacement elastomeric seal. With our metallic seal system weight fluctuation is virtually non-existent, unlike elastomeric seal. where weight fluctuation is a constant issue. Besides jet engines, our seal system will work in various other applications, including: fire doors installed in ships and commercial public or private buildings, such as banks, jewelry stores, auction houses, bomb shelters, and private security doors.
The Patent is available for licensing or outright purchase. Please contact Ron Alan McCormick by Email (or by phone shown above) for further information or to discuss your particular needs. We look forward to finding a solution for your application.
Fire Seals
Problem:
Currently the aircraft in-service and future aircraft are still using old school technology for the Fire Seals while the airframes and engines are developing new technology.
Fire Seals are used to contain fire within a compartment
The old school elastomeric are limited to a temperature of 500°F while the high performance engines are operating at high temperatures:-
1. Making it difficult to comply with the fire containment requirements.
2. Increased weight because additional thermal blankets are added to cover the seals for fire test.
3. Resulting in additional fire test and increase frequency of inspection intervals.
The limitations of the elastomeric seal has results in airline having to inspect Fire Seals at lower interval.
1. There are very low damage allowable limits for the seals resulting in unscheduled replacements at a cost.
Solution:
MHTSS High Temperature Seal Systems have developed metallic seal system to replace the elastomeric seals.
This video shows a simple fire test where the MHTSS contains extreme fire and the elastomeric seal failing immediately .
The MHTSS will:
1. Reduce weight.
2. Meet all fire containment requirements with minimum testing.
3. Reduces frequency of inspection intervals hence reduced direct maintenance cost for the airlines.
4. Lower cost and environmental friendlier
