New concept of aircraft has the INEGI engineering

From June 17 to 23, INEGI will be at the International Paris Air Show to present Flexible Aircraft, a new aircraft concept based on the idea of modularity.

With a cabin capable of reconfiguring itself for the transport of people or merchandise, or for civil protection missions (police, firefighters or medical emergency), the airplane will be 13 meters long and capable of holding 10 passengers. Ease of operation, speed and low consumption will also be among the characteristics of the new aerial vehicle.

The concept product is being validated in the FLEXCRAFT project, in three lines of development: "Flight and Operation", to define the aircraft final configuration and to study its dynamics of flight; "Versatility and Usability", to work the internal organization on board, modularity and flexibility; and "Production Materials and Processes", to evaluate which materials and processes are able to guarantee competitive costs and the desired performance.

INEGI is working in the scope of this last line. "We made the mechanical characterization of different carbon composites certified for aerospace use and compared four manufacturing processes", explains Rui Gomes, responsible for the project at INEGI. "This study led to the ion of the material and process to be used for the creation of a demonstrator componente, whose development was supported by advanced simulation tools", he said.

The process ed was the resin transfer molding (RTM), which guarantees the out-of-autoclave production in a single phase (one-shot process), which results in a reduction of costs, fulfilling the same quality parameters. This process was further optimized with tool sensoring, for monitoring of pressure and temperature in real time during production. The demonstrator produced - tail wing of the FLEXCRAFT aircraft - will be on display, from 17 to 23 June, at the International Paris Air Show (hall 3, stand C39).

The FLEXCRAFT project, co-promoted by INEGI, SET (Engineering and Transformation Society S.A.), Almadesign, Embraer Portugal and Instituto Superior Técnico, has been in development since the end of 2016 and will finish this year. The initiative is co-financed by the COMPETE 2020 programme, within the scope of the Research and Technological Development Support System (Business R & D) in co-promotion.
