“…Hence, the slot in the propeller will appear as a groove along the propeller blade. The chosen slot location of 0.62.5C and its slot dimension significantly impact the performance compared to other locations and the baseline design, as shown on published preliminary work done earlier [28][29][30].…”

“…The propeller's simulation is conducted and analyzed using Computational Fluid Dynamics software, ANSYS Fluent version 18.0. Computational parameters based on Table 3 need to be set for the simulation, similar to work published by Kutty and Rajendran et al, [30]. Second-order upwind Interpolating scheme(turbulence kinetic energy) First order upwind Interpolating scheme(specific dissipation rate) First order upwind The simulation's flow domain is divided into 2, the rotating domain which enables the propeller to rotate and the stationary domain.…”

The usage of slots has gained renewed interest in aerospace, particularly on propeller design. Most of the works have focused on improving the aerodynamic performance and efficiency. Modern research on propeller design aims to design propellers with high thrust performance under low torque conditions without any weight penalty. Although research on slotted design has been done before, none has been done to understand its impact on different airfoils on the propeller blade. Thus, this study aims to provide extensive research on slotted propeller design with various airfoil of different properties such as high Reynolds number, low Reynolds number, symmetrical, asymmetrical high lift, and low drag. This work has been investigated using computational fluid dynamics method to predict propeller performance for a small-scale propeller. The slotted blade designs' performance is presented in terms of thrust coefficient, power coefficient, efficiency, and thrust to power ratio. Here, the slotted APC Slow Flyer propeller blade's performance has been investigated for diverse types of airfoils with the shape and position of the slot is fixed which is a square-shaped at 62.5% of the chord length. The flow simulations are performed through three-dimensional computational fluid dynamic software (ANSYS Fluent) to determine the thrust coefficient, power coefficient, efficiency, and thrust to power ratio measured in advancing flow conditions. Findings show that the slotted propeller design composed of symmetrical, high Reynolds number, high lift airfoils can benefit the most with slots' implementation. These improvements were 19.49%, 69.13%, 53.57% and 111.06% in terms of thrust, power, efficiency and trust to power ratio respectively.

“…Thus, an intermediate and a fine quality three-dimensional mesh were created for the full UAV models having approximately over 4 million elements. A sufficiently large number of elements were selected in constructing the mesh for all the UAV models such that the models are indifferent to grid density and the maximum computed value of the wall unit, y+, approaches to 1 [13]. An efficient grid density from the surface of the model to the far-off region is necessary to conserve the computational time and to enhance the accuracy of the results at the interface of the solid models.…”

In this study, unmanned aerial vehicle (UAV) design, analysis and production was made using selective laser sintering (SLS) system. Four different aircraft bodies were designed in the interdisciplinary project, one of the models was selected by comparing the computational fluid dynamics (CFD) analysis results. According to the numerical study, the model 4 design was found to be the most suitable among the tested models, then the design was produced with the SLS system. Finally, the actual flight test was carried out in three different weather conditions, and the results are presented here.

Today the aircraft engine designing and development work is increasing drastically. Especially aircraft engines play a vital role in order to decide the aircrafts speed and its performance. Broadly turbojet, turboprop, turbo shaft and turbofan engines comes under the category of air breathing engines. Every engine has its own purpose and application. But modern aircrafts require much more advancements. Designing a new aircraft engine has been a really challenging task to the researchers. But giving a complete holistic view of aircraft engines and research gap would definitely help a lot to the new designers. Once identified the drawbacks of engine performance can be corrected in the future. For any new design of aircraft engine researchers are suggested to take Theoretical, Experimental and Numerical approaches. Therefore present paper makes an effort to review complete recent Theoretical, Experimental and Numerical approaches which are followed till date. Under all the three approaches all the air breathing engines have been clearly explained and solicited. The effort is to identify the gaps between different approaches which are hampering the process of engine development. The paper also gives the research gaps that need to be incorporated for effective performance enhancement of the aircraft engines for aeromechanical features.
