FEA Online is an approved supplier for:



MESSIER-DOWTY LTD (M-DL):

M-DL, member company of the SAFRAN Group, is the world leader in the design, development, manufacture and support of landing gear systems, garnering annual sales of € 594 million. Backed by a workforce of nearly 3,000 employees at 8 locations across Europe, North America and Asia, Messier-Dowty landing gear are in service on more than 19,000 aircraft making over 30,000 landings every day.

After a rigorous selection procedure FEA Online were awarded approved supplier status for complex FEA analysis of undercarriage components. FEA Online was able to demonstrate to M-DL that it could provide analysis capabilities that would match its own stringent requirements.

FEA Online was able to demonstrate that it could:-

• Successfully import and 'heal' M-DL CAD geometry prior to FE meshing.
• Mesh components according to M-DL requirements, including specific mesh densities in key component areas (see right).
• Apply loads and constraints according to accepted M-DL internal practices (force-balance, fully resolved forces, etc)
• Meet or exceed M-DL quality checking during each phase of the above.

Note: all results, FE models, reports and all other project output were presented via secure web pages, updated daily (see 'our service' page for more details).

Tom Siddall, Analysis Manager:

"The work that FEA Online has done has been excellent. Everyone at M-DL has been pleased with the results. I have used the results website and I am very impressed with it"

SMITHS AEROSPACE ELECTRONIC SYSTEMS, SOUTHAMPTON (SAES-S UK):

SAES-S is a leading global provider of innovative solutions to builders and operators of military and civil aircraft and engines, from fighters and transport to large civil, regional and business jets. They are the leading transatlantic aerospace equipment and systems company, with more than 10,000 staff and nearly $2bn revenues split between Europe and North America. Their business has a unique range of specialisations to create affordable, integrated systems, drawing on expertise in digital, electrical and mechanical systems, engine components and customer services. Their global customer services organisation supports 1,500 customers in 140 countries through a network of regional centers.

FEA Online was selected by Smiths Aerospace Electronic Systems, Southampton (SAES-S) to provide FEA support for the development of their unique Engine Distress Monitoring System (EDMS). This ongoing project involves the use of complex high temperature and contact analysis techniques.

Some of the types of analysis conducted for this project:-

• High temperature analysis consistent with operations within military jet engine exhaust environments
• Contact
• Vibration

Note: As part of this project FEA Online were required to meet US DoD International Traffic in Arms Regulations (ITAR) regulations.
