Abstract

The compressed air system is also called a vital system because it functions as a provider of compressed air for activities such as lifting and holding, turning and pressing, and even can be used for cleaning. In addition to those activities, it can also be used as a supply to the cabin pressurization simulation tool so that the pressure in the cabin can match the pressure of the aircraft when it is on the ground.This final project entitled "Design of a Compressed Air System for Cabin Pressurization and Student Practices" designed a compressed air system that will be used to simulate cabin pressurization by examining the appropriate components and calculating pressure losses in the system. The results of the preparation of this final project are expected to be useful to help provide an overview of the compressed air system and the manufacture of a pressurized air distribution system in Polban Aeronautical Engineering hangar.                                                                                                       Keywords: System, distribution, compressed air, pipes, cabin pressurization

Abstract

This research discusses the application of generative design on mountain bike frames using Solidworks and MATLAB Simulink software. The topic is taken from the problem of the inertial force that occurs in the structure of a mountain bike due to the dynamic forces that work. In the implementation, several things were carried out, namely the first to design the geometry of the mountain bike frame and determine the static load using solidworks software. Second, bicycle track modeling and dynamic load determination method using MATLAB simulink software. Third, numerical simulation on mountain bike frames with static and dynamic loads using solidworks. Thus, in this research a computational study was carried out using Solidworks and MATLAB simulink software. From the computational study, the results of different dynamic forces are obtained at each loading. At a maximum of mass of 90 kg the rider produces a static force of 1695,1 N and a dynamic force of 36,78 N. Under these loading conditions, a positive margin of safety is obtained so that the frame design of a mountain bike is declared safety.Keywords: Generative, Bike Frame, Solidworks, MATLAB simulink

Abstract

This research contains about how much the increase in the strength of the coconut fiber composite material as a result of the press hand lay-up method with post-curing treatment on the variable duration of heat curing. With a duration of 60, 120, 180 minutes, heat curing will find out which variation has the best effectiveness, considering several factors to increase the strength of composite materials, one of which is heat curing treatment can make coconut fiber composites have higher tensile strength values and are able to utilizing coconut fiber waste which is more useful than usual as an embodiment of 3R (reuse, recycle, reduce.) through methods commonly used for composite manufacture in general and focusing on the percentage increase in post-curing results will be a reference and reference for further research to realize the creation of coconut fiber composite which is more useful. The process of making coconut fiber composites in this TA uses the press hand lay-up method, with alkalization soaking first and then post-curing treatment using an oven with a constant temperature of 100°C. To find the specifications and the percentage of this strength increase factor is by means of a tensile test with the parameters obtained: Ultimate Tensile Strength, strain, modulus of elasticity, and poisson ratio. With the highest result is at a duration of 3 hours worth 47.09 MPaKeywords: composite, Resin Polyester, coconut fiber, tensile test, heat curing, post-curing

Abstract

This journal discusses the airfoil simulation on a helix type vertical turbine blade. The airfoils used are NACA 0018 and 4418. The simulation uses a Computational Fluid dynamics (CFD) application. In this simulation, TSR values are entered starting from 3.5, 3.8, 4.1, 4.4, 4.7, 5.0, 5.3, 5.6, 5.9, 6.2, 6.5. The results of the simulation show that the highest inhibition coefficient value is at TSR = 5.3 with a  value = 1.631 and for NACA 0018, and for NACA 4418, the highest inhibition coefficient value is at TSR 6.5 with a  value = 1.582. In the calculation results, the highest drag force (Fd) is at TSR 3.5 of 0.678 Newton at NACA 0018 with a turbine power of 10.78 Watt with a value of  = 0.35, turbine efficiency 35%.Keywords : Airfoil, TSR, NACA, TASV, CFD

Abstract

EDF (Electric Ducted Fan) is an electric-powered propulsion engine that is considered efficient in optimizing propulsion and aerodynamic forces on the fan. Beside the ducts addition in the fan area, the addition of ducts in other areas such as outlets can also affected the EDF performance. The 90mm EDF when normal conditions (factory settings) does not have a duct to direct the airflow out of the system. The implementation of this experimental study includes the manufacture of outlet duct geometry which is made in 3 variants of shapes (cylinder, covergent, convergent-divergent). Geometry is made using Solidwork software. Manufacturing activities are carried out using the 3D Printing method using  PLA (Polylactic Acid) type material. And testing activities are carried out under static testing conditions using a thrust meter. The result of this final project, there is a significant effect after the outlet duct addition on the EDF is given. The effect that occurs is a thrust value reduction by 6.65% to 48.64%.                                                                          Keyword: Experimental, EDF, Outlet Duct, Thrust

Abstract

In this day, composites has been widely used. Composites are used to reduce weight and increase the strength of the bicycle frame while minimizing costs. This is because composites are known as strong and lightweight materials. Apart from that, the costs incurred when making composites are much cheaper than using aluminum alloy material to make bicycles. One type of composite that is suitable for use in problems that exist in bicycle frames is composite carbon fibre combined with epoxy resin. Therefore, in this final project the author will make a bicycle frame using a composite material with a combination of fibre in the form of carbon fibre and a matrix in the form of epoxy resin. In the manufacturing process, the author also made modifications to the technique of making the bicycle frame. The method used is the wet lamination method, while the modification made is the process where the wet lamination is carried out in the direction of the rolled fibre. In the end, identification will be carried out by comparing the bicycle frame made with carbon composite material and the conventional bicycle frame made with aluminum alloy material.                                                                                                               Keywords : Bicycle Frame, Carbon Composite, Wet Lamination Method
