Eurocopter Tiger
Main Landing Gear

The main landing gears are fitted on the front of the Tiger helicopter.
The landing gear supports a helicopter of 6100 kg.
The Tiger main gear has a capability to withstand crash conditions under a vertical speed of 10.5 m/s.
Since 2000, Messier-Dowty has supplied around 70 sets to Eurocopter

Messier-Dowty’s selection for the Boeing 787 landing gear will be the company’s first prime contract with Boeing for a commercial aircraft and is the culmination of some 12 years of teamwork, working closely with Boeing in support of their product development studies.

Messier-Dowty will be responsible for the design, development, testing, manufacture and integration of the main and nose landing gear structure.

The 787 program is different to previous commercial bids with Boeing, in that Messier-Dowty will be responsible for the design in addition to the manufacture of the gear. Messier-Dowty offered several optional features to Boeing, each based on one of the following areas: new materials, environment, low cost and low weight. The company continues to work with Boeing to define the configuration that best works for the 787.

Messier-Dowty and Boeing will be working together as a single Life Cycle Product Team (LCPT) to optimize the landing gear designs which will include:

- Material trade studies to achieve minimum landing gear weight including increased use of Titanium and, on the main gear, potential fiber reinforced composite applications
- Environmentally acceptable alternatives to Chromium and Cadmium
- Advanced design features aimed at ensuring maximum reliability and maintainability
- Corrosion free solutions based on increased use of Titanium and Corrosion resistant steels

The Design activity will now all be based out of the Seattle office with Engineers from Toronto, Gloucester, Velizy and other Safran Group companies relocated to assist the team through the peak years of the development activity.
