Towards computational flight dynamics of a passenger jet aircraft
Towards computational flight dynamics of a passenger jet aircraft
This paper investigates the efficient generation of an aerodynamic database for flight simulation of a regional jet aircraft. A hierarchy of aerodynamic models is used, from semi–empirical approaches up to computational fluid dynamics analyses. The prediction tools are first validated at both low and high speeds against wind tunnel measurements. To reduce the number and costs of computational fluid dynamics calculations, Kriging interpolation is exploited to generate the aerodynamic tables. Data fusion allows combining different aerodynamic sources into one single database that is more accurate than each single database. The longitudinal and lateral handling qualities are first investigated for the regional jet aircraft. Then, the impact of geometry changes on the aircraft dynamic characteristics is investigated. It is found that improved aircraft characteristics could be achieved for relatively small changes relative to the baseline geometry.

Abstract
This paper investigates the efficient generation of an aerodynamic database for flight simulation of a regional jet aircraft. A hierarchy of aerodynamic models is used, from semi–empirical approaches up to computational fluid dynamics analyses. The prediction tools are first validated at both low and high speeds against wind tunnel measurements. To reduce the number and costs of computational fluid dynamics calculations, Kriging interpolation is exploited to generate the aerodynamic tables. Data fusion allows combining different aerodynamic sources into one single database that is more accurate than each single database. The longitudinal and lateral handling qualities are first investigated for the regional jet aircraft. Then, the impact of geometry changes on the aircraft dynamic characteristics is investigated. It is found that improved aircraft characteristics could be achieved for relatively small changes relative to the baseline geometry.
