The work in this paper primarily focuses on the modelling and analysis of a plane's propeller blade for strength. The geometry of a propeller blade is a sophisticated 3D model. CATIA V5 R20 is utilised to generate the blade model, which necessitates the usage of high-end modelling CAD software. This document provides a brief overview of Fiber Reinforced Plastic materials as well as the benefits of employing composite propellers over traditional metallic propeller blades. The purpose of this research is to use finite element analysis to analyse the metal and composite strength of the propeller blade. We conducted static and modal analysis for isotropic materials using ANSYS software, as well as linear layer analysis for orthotropic materials. FEA methods were used to investigate two distinct types of propellers, namely aluminium, E-glass, and carbon fibre.

An apparatus that moves heat from one fluid to another is a heat exchanger. To avoid mixing, the fluids may be separated by a solid wall, or they may be in direct touchHairpin Exchangers are available in bare tubes, finned tubes, U-tubes, straight tubes (with rod-thru capability), fixed tube sheets, and detachable bundles. They also come in single tubes (Double Pipe) and numerous tubes within a hairpin shell (Multitude). The combination characteristics of nano fluid and base fluid water are calculated in this article. Magnesium Oxide and silver nano particle volume fractions of 0.35, 0.45, 0.55, and 0.65 percent at varied velocities (0.5, 1,1.5, and 2 m/s) were used as nano fluids. The properties of nanofluids are calculated theoretically, and the results are used as inputs for analysisA 3D model of the hair pin heat exchanger with and without twisted tape is made using CREO parametric software. CFD analysis of the hair pin heat exchanger is performed at different nanofluid volume fractions. The pressure drop, Reynolds number, heat transfer coefficient, and Nusselt number are all determined using CFD analysis.

Composite materials are created by carefully combining two or more components to get a beneficial result. a system of materials made up of two or more physically distinct phases that, when combined, create aggregate properties that are distinct from those of their individual components. The fibre’s function is to give the product strength, bind the filaments together into a matrix, and shield the fibres from the elements. On a weight-to-weight ratio, composites are a class of materials that are stronger and more rigid than any other traditional engineering material. We employ in daily life. Other extremely intriguing options for further weight reduction include altering the volume proportion of fibre and resin in the component and aligning the orientation of the fibre along the direction of load. To create the hybrid natural fibre composites, the current experimental investigation intends to. Samples of a variety of jute, basalt, and polyester hybrid natural fibres will be created utilising the hand layup process, where the weight fraction of the fibre matrix is at various percentages and the stacking of the plies is alternated. Composites' void content rises as both the fibre loading and the fibre length increase. Composites with a 25wt% fibre loading demonstrate a better hardness value as far as the influence of fibre loading is concerned. Tensile strength diminishes after 25%, hence tensile modulus is appropriate for average weight percentage of fibre loading, or 25wt%.
