Development of an Adaptive Aero-Propulsive Performance Model in Cruise Flight – Application to the Cessna Citation X [PDF]
INCAS Bulletin, 2022 To accurately predict the amount of fuel needed by an aircraft for a given flight, a performance model must account for engine and airframe degradation. This paper presents a methodology to identify an aero-propulsive model to predict the fuel flow of an

Numerical Analysis of the Effect of the Non-Sinusoidal Trajectories on the Propulsive Performance of a Bionic Hydrofoil [PDF]
Journal of Applied Fluid Mechanics, 2022 Aquatic animals usually generate the effective propulsive force via non-sinusoidally flapping their fins. Inspired by the kinematics of fish, the propulsive characteristics of a NACA012 hydrofoil is numerically studied in this paper.

Propulsive performance of two- and three-dimensional flapping flexible plates
Theoretical and Applied Mechanics Letters, 2015 The propulsive performance of two- and three-dimensional (2D and 3D) flapping flexible plates in a fluid at rest is investigated by a finite element method for the plate motion and an immersed boundary-lattice Boltzmann method for the fluid flow.
