“…The analysis carried out here is associated with hovering and cruising conditions, which should give further awareness on and can be further elaborated into Coandă MAV maneuvering performance. The baseline analysis on Coandă MAV spherical configuration carried out here refers to and confirms the authors' previous analysis [31][32][33][34][35].…”

“…For convenience, in line with the rationale elaborated in [31][32][33][34], an indicator of the effectiveness of the Coandă jet device (MAV) to produce lift from rotor-like momentum rate input from the ambient air, a Performance Measure PM can be defined. Following the previous development and different from [31][32][33][34], a new Performance Measure P M can be defined as…”

“…Such Coandă jet has been utilized for circulation enhancement for fixed-wing aircraft in forward flight and turbine blades movement [4][5][6][7][8][9][12][13][14][15][16][17][18][19][20]. Thus, lift will be generated [27][28][29][30][31][32][33][34][35], which can be utilized for hover and later for cruise propulsion [10,35,36]. The principle of Coandă MAV lift generation as well as the equation of motion for its translatory motion will be derived and elaborated.…”

With the increasing need of micro-air-vehicles (MAVs) and advances in MAV technology, Coandă MAVs offer new promises and challenges. In this context, Coandă MAVs capabilities are analyzed. As a baseline, a mathematical model for a spherical Coandă MAV in hover and translatory motion is developed and analyzed from first physical principles. A computational fluid dynamic (CFD) simulations for a Coandă MAV generic model are carried out to assess the theoretical prediction and obtaining further physical insight on the Coandă MAV flow physics. The mathematical model and performance measures are developed to assess the capability of the semi-spherical Coandă MAV in performing effective flight as an aerial robotic platform, as indicated by the relationships between the relevant parameters of the mathematical model of the Coandă MAV to its system of flight forces.

Purpose-The purpose of this paper is to reformulate the governing equations incorporating major variables and parameters for the design a Micro Air Vehicle (MAV), to meet the desired mission and design requirements. Design/methodology/approach-Mathematical models for various spherical and cylindrical Coanda˘ MAV configurations were rederived from first principles, and the performance measures were defined. To verify the theoretical prediction to a certain extent, a computational fluid dynamic (CFD) simulation for a Coanda˘ MAV generic models was performed. Findings-The major variables and parameters of Coanda˘ MAV have been formulated into practical guidelines, which relate the lift (or thrust) produced for certain input variables, particularly the Coanda˘ MAV jet momentum coefficient. The influences of the geometrical parameters are elaborated. Research limitations/implications-The present analysis on Coanda˘ jet-configured MAV is focused on the lift generation due to the Coanda˘ jet effect through a meticulous analysis. The effects of viscosity, the Coanda˘ jet thickness, the radius of curvature of the surface and the stability of Coanda˘ jet are not considered and will be the subject of the following work. Practical implications-The results obtained can be used for sizing in the preliminary design of Coanda˘ MAVs. Originality/value-Physical and mathematical models were developed which can describe the physical phenomena of the flow field near the Coanda˘ MAV surfaces influenced by Coanda˘ jet sheets and for obtaining a relationship between relevant variables and parameters to the lift of practical interest.

Coandă effect, which has been widely utilized in many engineering applications for circulation control, is here reviewed for the design of Coandă Micro-Air-Vehicles (MAVs). Based on the review, a basic spherical configuration is analyzed to obtain the relationship between relevant parameters to the lift that can be produced based on fundamental principles. The results can be used for preliminary design purposes and are discussed in view of existing literature.
