Student,Dept. of Mechanical EngineeringRaghu Engineering College (A),Bheemunipatnam, Vishakapatnam,Andhra Pradesh, pin code 531162, IndiaAbstract: A propeller is a type of fan that transmits power byconverting rotational motion into thrust. A pressuredifference is produced between the forward and rear surfacesof the airfoil-shaped blade, and a fluid (such as air) isaccelerated behind the blade. Propeller dynamics can bemodeled by both Bernoulli's principle and Newton's third law.Aircraft propeller is sometimes colloquially known as an airscrew propellerThe present work is directed towards the study of compositeaircraft propeller working and its terminology, simulationand flow simulation of composite aircraft propeller has beenperformed.

AircraftAn aircraft is a machine that is able to fly by gaining supportfrom the air. It counters the force of gravity by usingeither static lift or by using the dynamic lift of an airfoil, or ina few cases the downward thrust from engines. Commonexamplesofaircraftinclude airplanes, helicopters, airships (including blimps), gliders, parameters and hot air.The human activity that surrounds aircraft is called aviation.The science of aviation, including designing and buildingaircraft, is called aeronautics. Crewed aircraft are flown byan onboard pilot, but unmanned aerial vehicles may beremotely controlled or self-controlled by onboard computers.Aircraft may be classified by different criteria, such as lifttype, aircraft propulsion, usage and others.2,*Amit Kumar MeharAssociate Professor,Dept. of Mechanical Engineering,Raghu Engineering College (A),Bheemunipatnam, Vishakapatnam,Andhra Pradesh, pin code 531162, IndiaPropeller aircraftPropeller aircraft use one or more propellers (airscrews) tocreate thrust in a forward direction. The propeller is usuallymounted in front of the power source in tractorconfiguration but can be mounted behind in lude contra-rotating propellers and ducted fans.Propeller bladeThrust is the force that moves the aircraft through the air.Thrust is generated by the propulsion system of the aircraft.There are different types of propulsion systems developthrust in different ways, although it usually generatedthrough some application of Newton's Third Law. Propelleris one of the propulsion systems. The purpose of thepropeller is to move the aircraft through the air. Thepropeller consists of two or more blades connected togetherby a hub. The hub serves to attach the blades to the engineshaft. .Propeller bladeThrust is the force that moves the aircraft through the air.Thrust is generated by the propulsion system of the aircraft.There are different types of propulsion systems developthrust in different ways, although it usually generatedthrough some application of Newton's Third Law.

Vibration defect can also be controlledin case of composite as damping effect is more. They haddone a comparison of harmonic analysis using ansyssoftware between aluminium metal and S2 Glassfabric/Epoxy. From their result maximum displacement incase of composite is 0.08192 which very less thanaluminium propeller blade 0.1784.M.A.Khan et al[2] observed inter laminar shear stress forcomposite material considering different no of layer andshows there is strong bonding between the layers. Eiganvalue analysis shows composite material has 80.5% morenatural frequency than aluminium propeller. In their staticanalysis they had shown composite consist of separatelayer.V Ganesh et al. [3] had done static and modal analysis foraluminium propeller and composite (carbon reinforcedplastics) propeller. From their analysis it shows bladedeflection in case composite propeller is very less compareto aluminium. Besides that they also observed the stressstrain variation for the strength analysis.General characteristics Crew: None Capacity: 68 kg (150 lb) payload Length: 5.85 m (19 ft 2 in) Wingspan: 8.54 m (28 ft 0 in) Height: 1.25 m (4 ft 1 in) Gross weight: 500 kg (1,100 lb) Airfoil: NACA 64 A 008 Powerplant: 1 Limbach L 550, 40 kW (47 hp)Performance Maximum speed: 8000rpm Endurance: 18 hours Service ceiling: 6,100 m (20,000 ft)Design specificationsINTRODUCTION TO CADComputer-aided design (CAD) is the use of computersystems (or workstations) to aid in the creation,modification, analysis, or optimization of a design. CADsoftware is used to increase the productivity of thedesigner, improve the quality of design, improvecommunications through documentation, and to create adatabase for manufacturing. CAD output is often in theform of electronic files for print, machining, or othermanufacturing operations. The term CADD (for ComputerAided Design and Drafting) is also used.INTRODUCTION TO CATIACATIA is an acronym for Computer Aided Threedimensional Interactive Application. It is one of the leading3D software used by organizations in multiple industriesranging from aerospace, automobile to consumer products.CATIA is a multi platform 3D software suite developed byDassault Systèmes, encompassing CAD, CAM as well asCAE. Dassault is a French engineering giant active in thefield of aviation, 3D design, 3D digital mock-ups, andproduct lifecycle management (PLM) software. CATIA is asolid modelling tool that unites the 3D parametric featureswith 2D tools and also addresses every design-tomanufacturing process. In addition to creating solid modelsand assemblies, CATIA also provides generatingorthographic, section, auxiliary, isometric or detailed 2Ddrawing views. It is also possible to generate modeldimensions and create reference dimensions in the drawingviews. The bi-directionally associative property of CATIAensures that the modifications made in the model arereflected in the drawing views and vice-versa.IJERTV9IS080147CASE1: aircraft propeller with 2 bladesCASE2: aircraft propeller with 3 bladesCASE3: aircraft propeller with 5 bladesINTRODUCTION TO FEAFinite element analysis is a method of solving, usuallyapproximately, certain problems in engineering andwww.ijert.org(This work is licensed under a Creative Commons Attribution 4.0 International License.)310

It is used mainly for problems for which no exactsolution, expressible in some mathematical form, isavailable. As such, it is a numerical rather than ananalytical method. Methods of this type are needed becauseanalytical methods cannot cope with the real, complicatedproblems that are met with in engineering. For example,engineering strength of materials or the mathematicaltheory of elasticity can be used to calculate analytically thestresses and strains in a bent beam, but neither will be verysuccessful in finding out what is happening in part of a carsuspension system during cornering.Structural AnalysisCase1: Aircraft propeller with 2 bladesImported modelMeshed modelANSYS Autodyn is computer simulation tool forsimulating the response of materials to short durationsevere loadings from impact, high pressure or explosions.ANSYS MechanicalANSYS Mechanical is a finite element analysis toolfor structural analysis, including linear, nonlinear anddynamic studies.
