Increasing efficiency of fatigue testing complex technical systems (for example, aircraft engine) is possible with its technical and economic assessment on base of relationship with the economic effect from the system operation. The amount of data is received during the engine life cycle. It should be properly processed to build the lifecycle model. Big Data concept can be suggested as an effective...
The focus of this paper is on the design, development and evaluation of a framework for a fixed-wing UAV to achieve efficient Circulation Control-based (CC) flights. The research presented in this paper is the natural outgrowth of results reported in [1] related to the design and development of an Air Supply Unit (ASU) and plenum design for CC-based Unmanned Aerial Vehicles (UAVs). The framework consists...
This paper presents the methodology and utility of an HEV plant model using Matlab-Simulink for testing the HCU (Hybrid control Unit) logics in dSPACE Hardware-in-loop environment. It also describes how requirements related to Hybrid Controller testing are addressed using the subject plant model. It further discuss about the requirements for Inputs to hybrid controller that are modeled in close loop...
The paper puts forward a new thinking of UAV flight safety ground test and evaluation. It elaborates possible and ways of applying the ground test to verify and evaluate the UAV flight safety. On one hand, through combination of UAV airborne equipment fault diagnosis and prediction and comprehensive testing of data link will greatly enhance the ability of UAV flight safety and save test time and cost...
Engine model is one of the most important part in HILS for ECU testing. There are shortages in normal ones, such as big framework and complex structure of software design which result in the immense calculated amount, disadvantage of hardware drive ability and bad real-time as well. In this article, the strong simulation function of MATLAB/SIMULINK was used. Engine model was built based on the mean...
The LRAFB C-130 engine repair facility is one of the top T-56 engine refurbishing plants in the United States Air Force. Currently, the shop is prevented from testing potential contingencies within their environment due to the rapid nature of their engine repair process. A simulation approach is needed to test various scenarios and determine the maximum capacity the shop can handle in its current...
The Department of Civil and Mechanical Engineering at the United States Military Academy requires its graduates to complete an integrative capstone design in their senior year. One of these projects involves the design, construction, testing, and demonstration of a small, highly autonomous, uninhabited aerial system (UAS). This particular capstone option was added to the list of available capstone...
Developing sustainable urban environments is complex as it requires consideration of interacting social, economic and environmental sustain ability factors. The task is made even more difficult by the wide variety of stakeholders (e.g. planners, architects, businesses and the public) that may be involved in the process and the lack of a common language for all to understand. This paper describes a...
Recently Piaggio developed a new scooter equipped with a revolutionary front suspension electronically controlled locking. It was critical to test and validate the design of this new control system before deployment to ensure high customer satisfaction and reducing warranty costs. Test on a HIL platform accelerates the verification and validation process. A validated HIL set-up, being a repeatable...
In the present study the air/fuel mixing in the EV17 burner exit used in the GT13E2 turbine was investigated by means Computational Fluid Dynamics (CFD). The objective of the study was to determine the air/fuel mixing in the original burner design (reference case), investigate the air/fuel mixing with modified premix hole pattern (different impulse ratio and number of holes and recommend a hole pattern...
