“…There are several kinds of inverse design methods with different flow calculation approaches and different choices of prescribed quantities. Based on different flow calculation approaches, the inverse method can be divided into the inviscid [26,27] or viscous [28][29][30][31][32][33][34][35] category, the compressible [6,31] or incompressible [1][2][3][4]8] category, and the two-dimensional [36,37] or three-dimensional [38][39][40] category. No matter the kind of IDM, the basic idea remains the same.…”

Hydraulic machinery with high performance is of great significance for energy saving. Its design is a very challenging job for designers, and the inverse design method is a competitive way to do the job. The three-dimensional inverse design method and its applications to hydraulic machinery are herein reviewed. The flow is calculated based on potential flow theory, and the blade shape is calculated based on flow-tangency condition according to the calculated flow velocity. We also explain flow control theory by suppression of secondary flow and cavitation based on careful tailoring of the blade loading distribution and stacking condition in the inverse design of hydraulic machinery. Suggestions about the main challenge and future prospective of the inverse design method are given.

“…In traditional methods, the blade is typically designed based on the analysis of the aerodynamic performance of a steam turbine under single and ideal working conditions to obtain the ideal shape, and the reliability is determined by analyzing the strength, modality and life (Dulau and Bica, 2014;Kim et al, 2013;Eleftheriou et al, 2017;Kaneko et al, 2017;Lucacci, 2017;Prabhunandan and Byregowda, 2018;Shukla and Harsha, 2015;Tanuma, 2017). However, during the operation, multiple complex loads cause the actual shape of the blade to deviate from the ideal blade shape obtained by the theoretical design (Zhu et al, 2017).…”

Abstract. The deformation of blades under complex loads of multiple working conditions will reduce the energy conversion efficiency. To reduce the deviation of the blade shape in practical working conditions, a combination and optimization method of blade design schemes under multiple working conditions, based on the entropy weight vague sets, is proposed. The sensitivity of each working condition index is analyzed based on the information entropy, and the satisfaction degree of the design scheme based on the design requirements and experiences is described with the vague set. The matching degree of different design schemes for multiple working conditions is quantified according to the scoring function. The combination and optimization of the design scheme are verified by numerical simulation analysis. The results show that the proposed design scheme has a smaller blade shape deviation than the traditional design scheme under multiple working conditions.

“…The analysis of these kind of systems can be performed using analytical, experimental and CFD tools [2? ]. A great deal of work has been performed using numerical methods for analysis and design of propulsion systems, and these can be directly applied in the present nozzle configuration [4][5][6][7][8]. The present system can be applied to heavier than air vehicles or even to airships [9,10].…”

A review of thrust-vectoring in support of a V/STOL non-moving mechanical propulsion system

Abstract:The advantages associated to Vertical Short-Take-Off and Landing (V/STOL) have been demonstrated since the early days of aviation, with the initial technolology being based on airships and later on helicopters and planes. Its operational advantages are enormous, being it in the field of military, humanitarian and rescue operations, or even in general aviation. Helicopters have limits in their maximum horizontal speed and classic V/STOL airplanes have problems associated with their large weight, due to the implementation of moving elements, when based on tilting rotors or turbojet vector mechanical oriented nozzles. A new alternative is proposed within the European Union Project ACHEON (Aerial Coanda High Efficiency Orienting-jet Nozzle). The project introduces a novel scheme to orient the jet that is free of moving elements. This is based on a Coanda effect nozzle supported in two fluid streams, also incorporating boundary layer plasma actuators to achieve larger deflection angles. Herein we introduce a state-of-the-art review of the concepts that have been proposed in the framework of jet orienting propulsion systems. This review allows to demonstrate the advantages of the new concept in comparison to competing technologies in use at present day, or of competing technologies under development worldwide.
