Abstract

Aircraft structures to be made stronger in order to be able to withstand the force received. The forces acting on the structure can cause deformation and result in structural failure. All components o f the structure o f the aircraft is an important part and it requires a good working resilience to maintain the security (safety). One important component of the aircraft that must be considered is the structure of the landing gear fittings. Fitting is contained in the structure that functions held their landing gear load received all the landing gear and as an intermediary for the landing gear and airframe structure of the aircraft. Because Landing Gear is one important component in the structure of the aircraft. Strength landing gear fittings will be calculated at the time of landing, the burden derived from the speed of the aircraft landing and aircraft load.

Abstract

Vertical Wind Tunnel (VWT) is a wind tunnel application that is directed vertically upwards, so that the air impulse is applied as an alternative to people (athletes) feeling the sensation of flying, like parachuting when jumping at altitude out of an airplanea. VWT will certainly reduce the potential for accidents, improve the efficiency of skydiving, and improve the quality of skydiving athletes. To ensure the design of the VWT structure is safe, it is necessary to test the strength of the structure with load = 55212.16 Newton and load thrust = 46826.3516 Newton. VWT structure uses 2 types of steel material, namely the type of Steel A36 and Steel A441 because this type has the appropriate material property other than that it is very easy to get on the market. then simulated using CATIA V5R21 software. So that the obtained value of Steel A36 Margin of Safety (MS) is 2.79 (load) and 3.48 (load thrust). For Steel A441, the MS value is 4.52 (load) and 5.51 (load thrust), from all the two materials producing an MS value> 1, indicating that the design of the VWT structure is said to be safe.

Abstract

The fusion of MIMU and GPS data is generally used to estimate the displacement and tracking of quadrotor UAVs. Meanwhile, displacement estimation inaccuracies during dynamic motion often occur. This error is caused by noise and limited sensor sampling rate especially occurs when the quadrotor changes its attitude rapidly to generate an instantaneous horizontal force. This paper proposes data fusion based on Kalman filter to estimate orientation and displacement. Experiments were also carried out to verify displacement accuracy, i.e. in single-axis and multi-axis sensor motions. The algorithm combines data from MIMU and GPS sensors so that acceleration data is filled in points where GPS data is not available. With this method, the predicted displacement from the MIMU sensor can be corrected every second with data from the GPS and produce accurate displacement and trajectory estimates.

Abstract

Traffic congestion in areas with two closely situated traffic lights is a complex issue that is often difficult to resolve. To address this issue, a coordination of timing between the two traffic controllers is proposed. This research conducts an experiment with two traffic controllers at two nearby intersections. The vehicle flow at each intersection is managed by the Agent acting as the traffic controller. The agent where more vehicles arrive is designated as the master agent, while the other agent is designated as the slave agent. A coordination algorithm is developed to synchronize the timing of the traffic controller so that the timing at the slave Agent was adjusted according to vehicle platoon arrivals from the master Agent. By this method, the green phase of the slave agent can be synchronized with the master agent, allowing vehicle platoons arriving from the master agent to immediately receive a green phase at the slave agent. This coordinated traffic control can be implemented with a microcontroller-based system, and vehicle movement can be simulated using Matlab's SimEvents. From the experiment conducted for two intersections located 500 meters apart, this scheme can reduce the average vehicle wait time from 40 seconds to just 9.4 seconds.
