Case Study Background<\/h3>\n

Leonardo SpA<\/a>, formerly known as Finmeccanica is an Italian multinational company specialising in aerospace, defence and security. Centred in Rome, it is located at 180 sites worldwide. The company is organised into the divisions: Helicopters, Aircraft, Aerostructures, Electronics, Security and Information Systems.<\/p>\n

The Helicopters division is based on the former independent companies Agusta and Westland. It performs research, design, development, production, customer support, pilot training and marketing of the company\u2019s extensive range of modern helicopters for the commercial, public service, and security and defence markets. The plants are physically located in Italy, the UK, Poland and the US.<\/p>\n

Requirement \u2013 flexible, compatible and tested numerical routines<\/h3>\n
\n

The\u00a0Helicopter Division<\/a>\u00a0endeavours to constantly expand the capability and performance of its products, and to integrate the latest technology into its programmes, creating, through research and development, a modern and technologically advanced range of rotorcraft. Because of this Leonardo continually invest in advanced computer software. Although some of the company\u2019s work utilises proprietary software, for example, in the areas of computational fluid dynamics or finite difference methods, because of its unique requirements\u00a0it has been necessary\u00a0to develop its own numerical code for the design, analysis and modelling of helicopter behaviour. Much of the code is written in Fortran, in conjunction with Unix scripts, and currently there are several hundred programs consisting of the order of 3 million lines of code, created and developed by both engineers and IT specialists, often by multiple contributors in parallel or sequentially over time.<\/p>\n

Solution \u2013 calling on n<\/i><\/span>AG Library numerical routines into existing software<\/h3>\n

The software is complex and often ground breaking. With this in mind, and to avoid re-inventing the wheel, the program developers access, with complete confidence, a large library of routines that offer a wide range of numerical and statistical routines. Leonardo Helicopters\u2019 internally-developed code calls\u00a0n<\/i><\/span>AG Library<\/a>\u00a0routines for the following tasks:<\/p>\n
