    Pontillo, Alessandro (Cranfield UniversitySATM, 2019-12-20)
    The aim of this work is to assess the aeroelastic response to gust of a flexible high aspect ratio wing (HARW) single-aisle commercial aircraft and to design a viable open-loop Gust Load Alleviation (GLA) system. ...
  • Identification of flexible structures dynamics. 
    Dessena, Gabriele (Cranfield UniversitySATM, 2023-04)
    The pursuit of aerodynamic efficiency and the advances in materials technology, particularly in composite material, has contributed to shifting the paradigm of wing design to high aspect ratio wings. Increasing the span, ...
  • Injectable venturi for slug control. 
    Inok, Joseph Otu (Cranfield UniversitySWEE, 2019-08)
    Severe slugging is a cyclic flow regime which causes intermittent delivery of oil and gas, which could lead to flow separator flooding, production reduction, platform trips and plant shutdown. The large and rapid variation ...
  • Longitudinal control laws design for a flying wing aircraft 
    Zhu, Yan. (Cranfield University, 2012-02)
    This research is concerned with the flight dynamic, pitch flight control and flying qualities assessment for the reference BWB aircraft. It aims to develop the longitudinal control laws which could satisfy the flying and ...
  • Model simulation suitable for an aircraft at high angle of attack 
    Mohmad Rouyan, Nurhana (Cranfield University, 2016-01)
    Simulation of a dynamic system is known to be sensitive to various factors and one of them could be the precision of model parameters. While the sensitivity of flight dynamic simulation to small changes in aerodynamic ...
