  • 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 ...
  • Multi-objective optimal longitudinal flight control system design for a large flexible transport aircraft. 
    Song, Sipeng (2018-05)
    This thesis presents a multi-objective evolutionary algorithm design of a longitudinal optimal controller for a large exible transport aircraft. The algorithm uses a mixed optimization approach based on a combination of ...
  • Multidisciplinary design optimisation for aircraft wing mass estimation 
    Dababneh, Odeh (Cranfield University, 2016-04)
    The implementation of key technologies in the initial stages of the aircraft wing design process has always represented a substantial challenge for aircraft designers. The lack of reliable and accessible wing mass prediction ...
  • New multiphase flow measurements for slug control. 
    Nnabuife, Godfrey Somtochukwu (Cranfield UniversitySWEE, 2019-01)
    Severe slug flow is undesirable in offshore oil production systems, particularly for late-life fields. Active control through choking is one of the effective approaches to mitigating/controlling severe slug flow in oil ...
  • A Novel Collision Avoidance Logic for Unmanned Aerial Vehicles Using Real-Time Trajectory Planning 
    Lai, Chi Kin (Cranfield University, 2014-10)
    An effective collision avoidance logic should prevent collision without excessive alerting. This requirement would be even more stringent for an automatic collision avoidance logic, which is probably required by ...
  • On the generation of environmentally efficient flight trajectories 
    McEnteggart, Quintain (Cranfield University, 2015-05)
    To achieve a sustainable future for air transport, the International Civil Aviation Organization has proposed goals for reductions in community noise impact, local air quality and climate impacting emissions. The goals ...
  • Optimisation methods for battery electric vehicle powertrain. 
    Othaganont, Pongpun (2017-07)
    The battery electric vehicle (BEV) is considered to be one of the solutions for reducing greenhouse gasses and an alternative means of transportation. However, some current limitations such as higher powertrain costs, ...
  • Propulsion and flight controls integration for the blended wing body aircraft 
    Ur Rahman, Naveed (Cranfield University, 2009-05)
    The Blended Wing Body (BWB) aircraft offers a number of aerodynamic perfor- mance advantages when compared with conventional configurations. However, while operating at low airspeeds with nominal static margins, the ...
  • Road vehicle state estimation using low-cost GPS/INS 
    Tin Leung, King (Cranfield University, 2010-04-12)
    Due to noise and bias in the Inertial Navigation System (INS), vehicle dynamics measurements using the INS are inaccurate. Although alternative methods involving the integration of INS with accurate Global Positioning ...
  • Robust gain-scheduled H [infinity] control for unmanned aerial vehicles 
    Chumalee, Sunan (Cranfield University, 2010-06)
    This thesis considers the problem of the design of robust gain-scheduled ight controllers for conventional xed-wing unmanned aerial vehicles (UAVs). The design approaches employ a linear parameter-varying (LPV) control ...
  • Towards Autonomy of a Quadrotor UAV 
    Cowling, Ian (Cranfield University, 2008-10)
    As the potential of unmanned aerial vehicles rapidly increases, there is a growing interest in rotary vehicles as well as fixed wing. The quadrotor is small agile rotary vehicle controlled by variable speed prop rotors. ...
  • Wake Vortex Modelling and Simulation for Air Vehicles in Close Formation Flight 
    Saban, Deborah (Cranfield University, 2010-01)
    The aim of this research is to develop realistic models of aerodynamic cross-coupling e ects that can be incorporated in real-time or near real-time simulations of Unmanned Aerial Vehicles (UAVs) in close formation flight. ...
