Abstract

In drone design, the selection of components such as batteries, Electronic Speed ​​Controllers and propellers must be in accordance with the requirements, but not all components in the RC include measurement data to determine the specifications of the brushless motor. Therefore, a test tool is needed that can calculate the amount of thrust or use a tool trials. Brushless motors and propellers are important components that affect flying performance on drones. The greater the thrust generated by the brushless motor and propeller, the greater the load that can be lifted by the drone. The types of propellers commonly used in drones include 6x4, 9x6, and 10x5 propellers. To measure the amount of thrust, load sensors and current sensors can be used which are converted by the ADC HX711 converter. The test bench tool can be used to produce data experimentally using the help of the sensor. In testing the 6x4e propeller produced a current of 7.8 Ampere and a thrust of 1.13 kgf, the 9x6e propeller produced a current of 16.4 Ampere and a thrust of 1.63 kgf, and the propeller 10x5e produced a current of 18.6 Amperes and a thrust of 2.07 kgf with the right selection of brushless motors and propellers, drone performance can increase.

Abstract

The aviation industry has recovered from the pandemic, and airlines are confidently operating their fleets again, one of which is the Bell 505 helicopter. Helicopter maintenance is also carried out to maintain performance in good condition and ready to fly. The performance of the Bell 505 helicopter is also influenced by the condition of the engine, if the engine is said to have good performance, the engine must be able to be used in function according to the planned time. In Bell 505, a problem was found during the implementation of the Power Assurance Check, namely, the decrease in the MGT margin value which is close to the value of 0, resulting in a decrease in the performance of the engine itself. Therefore, analysis and corrective action are needed to determine the cause of the decrease in the MGT margin of the Arrius 2R engine. The method used is fault tree analysis, by taking a top down approach, starting with the assumption of failure from the Top Event then detailing down to the basic failure (Root Cause). After drawing the FTA construction, evaluation is carried out with the Minimum Cut Set until the basic event is obtained. The results of the analysis conducted with “Decrease in MGT Margin Engine Arrius 2R" as the Top Event on the Bell 505 Jet Ranger X helicopter with registration code PK-WSA in the period March 2022 to July 2022 at PT.Whitesky Aviation based on AFML (Aircraft Flight Maintenance Log) data, Interview with Bell 505 Engineer and Troubleshooting Manual Engine Arrius 2R using the Fault Tree Analysis method obtained, 13 intermediate events using the logic gate “OR” and 9 basic events that cause a decrease in MGT margin on the Arrius 2R Engine are Broken Packing Seal, Fuel Contamination, Issues With the Fuel Filter, Environmental Conditions, Filter Damage, Filter Deterioration, Un Tight Screw, IBF Rarely Cleaned, Not Familiar Maintenance Manual.

Abstract

The rocket development process goes through several stages with the aim of ensuring rocket performance when simulated. One of the important stages in the rocket development process is knowing the aerodynamics on the rocket. Aerodynamics on rockets need to be known because they affect performance when the rocket is simulated. To obtain the results of aerodynamic analysis on rockets, analysis is needed on CM (Coefficient of Moment), CD (Coefficient of Drag), and CL (Coefficient Lift) prices. In this study, the object used was FFAR (Folding Fin Aerial Rocket) with a diameter of 70 mm. The aerodynamic analysis process is carried out through simulation with two software, namely SimScale and Datcom Missile. . The results of aerodynamic analysis on rockets by varying the time(s) and speed in simulations using SimScale showed quite convergent results with movements at Mach 0.1, 0.2, and 0.3 approaching each other. While the simulation results on the Datcom missile by varying the angle of attack (α) and speed also showed convergent results with movements at Mach 0.1, 0.2, and 0.3 approaching each other.

Abstract

To determine the effect of temperature variations on mixing fiberglass composite resin materials with the vacuum infusion method in the Tensile test. To determine the effect of the lowest and best temperature variations on mixing fiberglass composite resin materials with the vacuum infusion method on fotomikro. Variation fixed resin; polyester, fiber; fiberglass, vacuum; vacuum Infusion. Variable temperature of mixing resin 30˚C, 40˚C, and 50˚C. In this study, the vacuum infusion method was used, where the researcher made a specimen using the Vacuum Assisted Resin Infusion (VARI) process. In the VARI process, dry fiber is placed between the fixmold and the plastic bag, then the resin is injected after the space inside the plastic bag is under low pressure and the process continues until all parts of the fiber are wetted by the resin. After the specimen is made, then a tensile test is carried out to determine the mechanical strength of the specimen being tested. Then analyze the tensile test data using the equations used and displayed in the form of graphs and tables. This study was used to determine the effect of fiberglass composites with the vacuum infusion method on the tensile strength test. results of Tensile testing of fiberglass fiber composites and temperature variations of 30°C, 40°C, and 50°C. From the table it can be seen that the specimen with the best performance is found in the specimen with a temperature variation of 50°C, where the load that can be withheld reaches 508.56 kgf. So for maximum tensile strength it produces 11.07 MPa. Then on the specimen with a temperature variation of 40°C the best performance is 361.95 kgf. So for maximum tensile strength it produces 8.46 MPa. In specimens with a temperature variation of 30°C the best performance is 251.10 kgf. So for a maximum tensile strength of 5.67 Mpa. The average yield strength shows the results of the Tensile test of each variation, totaling 9 specimens. For the highest yield strength, a value of 9.67 MPa was obtained at a temperature variation of 50°C and for the lowest yield strength, a value of 4.13 MPa was obtained at a temperature variation of 30°C. Tensile test specimens have results where the highest yield strength or yield strength is obtained by specimens with a temperature variation of 50°C and as the stress increases, the yield strength value increases, and for the tensile strength of the material or tensile strength which has the highest value in the test, the specimens with 50°C temperature variation. Thus, the effect of temperature treatment is significant on the increase in tensile strength, but if the temperature is 30°C it will decrease the tensile strength, as at 30°C it produces an average tensile strength of 4.62 MPa. The results of the microphoto test show that at a temperature variation of 50°C there are a few voids while the 30°C variation has too many voids. Micro photo testing aims to determine the content in the composite.
