  • Exergy methods for commercial aircraft integrating the laws of thermodynamics into all disciplines of aircraft design. 
    Hayes, David (2018-07)
    As a consequence of practicalities, work share and difficulties in designing complex aerospace systems, there has been historical segregation of sub-systems in aircraft design. This methodology has proved successful for ...
  • A fault Hiding Approach for Fault Tolerant Control of a Class of VTOL Vehicles 
    Marks, Aryeh (Cranfield University, 2015-02)
    The octorotor is an unmanned VTOL capable vehicle with eight motors with xed pitch rotors. It is controlled by varying the speeds of its eight motors which are placed around the vehicle. There is no need for a complex ...
  • Flight desk control demonstrator 
    Duran, Joris Rene (2018-08)
    The aim of a control system is to obtain a desired output response according to an input command. This can be achieved by knowing a model of the system with an open-loop control. However, an accurate model can be difficult ...
  • Gain scheduling for a passenger aircraft control system to satisfy handling qualities 
    Guo, Wei (Cranfield University, 2010-12)

  • High aspect ratio wings on commercial aircraft: a numerical and experimental approach 
    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 ...
