In this paper, aerodynamics and flight dynamic stability of the four-winged FMAV was studied experimentally and numerically. The paper is organized as follows: firstly, both experimental as well as numerical me
it won three German race championships. Next to appear was the NSU Ro 80, a revolutionary design in every way and the first German model to be voted “Car of the Year”. But then came 21 August 1969, when Audi and NSU agreed to join forces and NSU ceased to be independent after almo...
As for the square cylinder, a critical angle of attack of approximately 13掳 is observed at which drag and fluctuating lift forces are minimised while mean lift and Strouhal number reach their highest values. Reattachment of the shear layer at and above the critical angle of attack is confirmed...
The company has also endeavored to address the number one criticism of electric vehicles: range.It has removed many of the luxurious features consumers expect in a normal car in favor of better aerodynamics.The Tesla Model S Long Range Plus, for example, has a range of 402 miles which is ...
Owing to their high flexibility, large scope and high frequency of wing flapping, insects with high flapping-frequency are of great importance for research on the aerodynamics of insect-flight [3]. Accordingly, motion parameters measurement of insects with high flapping-frequency is an important ...
Aerospace Engineering:In aircraftdesign, the systems boundary separates the aircraft (the system) from its surrounding atmosphere (the external environment). This boundary helps engineersanalyzeaerodynamics and flight characteristics. Software Development:The boundary in software development separates the custom...
The difference between the sub-tasks lies in the constraining forces. While driving, the user is constrained to a fixed distance above the ground. The underling terrain dictates entity pitch and roll, limiting user control of the eye point motion to three DOF, X, Y, heading. The other three...

aerodynamicsbicycle racing wheelsCFDAerodynamic drag is the main source of losses in cycling so improving the bicycle aerodynamic is a fundamental key factor to increase the performance. The aim of this work is to assess the capability of CFD RANS simulations to predict the aerodynamic performance ...
Design of flapping-wing micro air-vehicles presents many engineering challenges. As observed by biologists, insects and birds exhibit complex three-dimensional wing motions. It is believed that these unique patterns of wing motion create favorable aerodynamic forces that enable these species to fly ...
