Aircrafts interior & Primary Structure

Aircrafts Interiors

Involved in many VIP cabin outfitting projects of large aircraft, numeric GmbH has gathered precious experience in a wide range of cabinetry ranging from stand-alone items to complex modules.

Complex cabin interior

As an engineering partner, the numeric team is able to offer the expertise of experienced engineers to solve all issues involved in the most complex cabin interior layout.

Based on customer Finite Element standards, reliable 3D models are built to simulate representative cabinetry behaviour. For critical items, these models are often backed-up by analytical calculations.

Allowable prediction and test correlations

We can offer to our customers services in cabinetry ranging from allowable prediction of standard parts and assembly to test correlation of complete modules, such as large wardrobes or galleys.

Fuselage and floor structure modification

With engineers coming from major OEM stress departments (Airbus and Embraer), the numeric team is able to address complex modification of primary structure in compliance with aeronautical certification authorities.

During the past 4 years, we have been mainly involved in floor structure modifications to fulfil the requirements of highly customised VIP aircraft cabin.

16G Seat installation

The numeric team has been involved in several projects of 16g VIP seat installation in large aircraft like Boeing 777, Airbus 319CJ and Boeing 747-8.

In order to pass certification we successfully achieved a test prediction of a modified floor structure for a 16g seat installation with detailed non-linear Finite Element analysis within a 5% margin.

Cargo item installation

We have been involved in many VIP aircraft outfitting projects, including cargo item installation (additional water tanks, electronic cargo racks) leading to primary structure modification / reinforcement.
