Asymmetric Stall and Control Effectiveness reduction Modeling for the Cessna Citation II

Since 2019, the FAA and the EASA impose to all airline pilots to follow, as part of their training, a stall and recovery training. To mitigate the risks, this training takes place in ground-based simulators. To make it happen, models of the aircraft behaviour at high angle of attack need to be developed. Among the different modeling approaches...

Distributed Approach for Aerodynamic Model Identification of the ICE Aircraft

High performance control allocation methods for the Innovative Control Effectors (ICE) aircraft require accurate onboard aerodynamic models, with preferably first order continuity. Simplotope B-Splines, an extension on Simplex B-Splines, have a high approximation power by using local basis functions. However, enforcing global continuity produces...

Full Flight Envelope Aerodynamic Modelling of the Cessna Citation II using Physical Splines

A new aviation legislation makes it mandatory for air-carrier pilots to go through stall recovery training on simulators. As a result, new aerodynamic modeling techniques are required to model complex non-linear behavior of the aircraft flight envelope. In 2005, the Multivariate Simplex B-Splines method was developed. MSBS are a true general...

Design, Identification and Implementation of a High-Fidelity Cessna Citation II Flight Simulation Model

As a result of new aviation legislation, from 2019 on all air-carrier pilots are obliged to go through flight simulator-based stall recovery training. For this reason the Control and Simulation division at Delft University of Technology has set up a task force to develop a new methodology for high-fidelity aircraft stall behavior modeling and...

Online Aerodynamic Model Identification using a Recursive Sequential Method for Multivariate Splines

Avoiding high computational loads is essential to online aerodynamic model identi- fication algorithms, which are at the heart of any model-based adaptive flight control system. Multivariate simplex B-spline (MVSB) methods are excellent function approximation tools for modeling the nonlinear aerodynamics of high performance aircraft. However,...

Global Nonlinear Model Identification with Multivariate Splines

At present, model based control systems play an essential role in many aspects of modern society. Application areas of model based control systems range from food processing to medical imaging, and from process control in oil refineries to the flight control systems of modern aircraft. Central to a model based control system is a mathematical...
