Effect of Wing-Wing Interaction on the Propulsive Performance of Two Flapping Wings at Biplane Configuration [PDF]
Applied Bionics and Biomechanics, 2018 The biplane counter-flapping wing is a special type of wing flapping which is inspired from the fish and insect in nature. The propulsive performance is one of the most important considerations for this kind of flapping wing.

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.

Comparison of Aero-Propulsive Performance Predictions for Distributed Propulsion Configurations [PDF]
55th AIAA Aerospace Sciences Meeting, 2017 NASA's X-57 "Maxwell" flight demonstrator incorporates distributed electric propulsion technologies in a design that will achieve a significant reduction in energy used in cruise flight. A substantial portion of these energy savings come from beneficial aerodynamic-propulsion interaction.

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

Propulsive performance of oscillating plates with time-periodic flexibility [PDF]
Journal of Fluid Mechanics, 2022 We use small-amplitude inviscid theory to study the swimming performance of a flexible flapping plate with time-varying flexibility. The stiffness of the plate oscillates at twice the frequency of the kinematics in order to maintain a symmetric motion ...
