  • Tejero, Fernando; MacManus, David; Heidebrecht, Alexander; Sheaf, Christopher T. (Cambridge University Press, 2024-04-29)
    Within the context of preliminary aerodynamic design with low order models, the methods have to meet requirements for rapid evaluations, accuracy and sometimes large design space bounds. This can be further compounded by ...
  • Robinson, Matthew; MacManus, David G.; Sheaf, Christopher T. (SAGE, 2018-04-02)
    To address the need for accurate nacelle drag estimation, an assessment has been made of different nacelle configurations used for drag evaluation. These include a sting mounted nacelle, a nacelle in free flow with an ...
  • Swarthout, Avery; MacManus, David; Tejero, Fernando; Matesanz García, Jesús; Boscagli, Luca; Sheaf, Christopher T. (ICAS, 2022-09-09)
    There are significant environmental and economic drivers for the development of more fuel-efficient commercial aircraft engines. The propulsive efficiency benefits of ultra-high bypass ratio turbofans may be counteracted ...
  • Tejero, Fernando; MacManus, David G.; Sanchez-Moreno, Francisco; Sheaf, Christopher T. (Elsevier, 2023-03-03)
    In the context of aircraft applications, the overall design process can be challenging due to the different aerodynamic requirements at several operating conditions and the total associated computational overhead. For this ...
  • Sanchez Moreno, Francisco; MacManus, David; Hueso Rebassa, Josep; Tejero, Fernando; Sheaf, Christopher T. (ICAS, 2022)
    The design and optimization of aero-engine nacelles in a configuration installed on the airframe may be an important consideration to realize the cycle benefits of new ultra-high bypass ratio aero-engines. However, this is ...
  • Tejero, Fernando; MacManus, David; Goulos, Ioannis; Sheaf, Christopher T. (Cambridge University Press, 2023-06-13)
    It is envisaged that future civil aero-engines will operate with ultra-high bypass ratios to reduce the specific fuel consumption. To achieve the expected benefits from the new engine cycles, these new powerplants may mount ...
  • Schreiner, B. Deneys J.; MacManus, David; Tejero, Fernando; Sánchez Moreno, Francisco; Sheaf, Christopher T. (ICAS, 2022-09-09)
    It is expected that future civil aero-engines will operate at low specific thrust and high-bypass ratios to improve propulsive efficiency. This may result in an increment in fan diameter and associated weight and nacelle ...
