After welding, high hardness values of the Heat-Affected Zones (HAZs) of these dissimilar weld joints are possibly obtained. The uneven hardness in HAZ comes from the austenite transformation to Martensite, because of highly uncontrolled cooling rates. The considerable difference in hardness among various zones leads to prior cracking and is bound to failure during high-temperature operations. Therefore, there is a dire need to establish an appropriate Post Weld Heat Treatment (PWHT) to temper the dissimilar weld joints for required durability. The study investigates the microstructure and mechanical properties of various erupted zones of steel, before and after the application of PWHT. Before and after PWHT, weld zone and HAZ in P22 and P91 are mechanically tested and metallurgically examined. Further PWHT is tried to be optimised strategically and statistically, for the least variation in hardness among different zones. So that any failure due to thermal stresses or strains, during normal running conditions can be avoided.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"146 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88635401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A real-time case study is carried out for the design configurations, propulsive systems, performance characteristics and structural integrity parameters of 26 distinct middle-of-the-market aircraft. Furthermore, a sensitivity analysis is carried out in order to validate the MTOW model. The model provides the best fitness with R2 = 0.9676.

This investigation is focused on the addition of different weight percentages of Al2O3 while keeping B4C constant with Al 6061 alloy and evaluating the mechanical properties by running tests like wear, hardness and microstructure. By observing the results, a conclusion was reached that the addition of reinforcements had successfully enhanced the composite or not.

To overcome such increment in geometry of a mini UAV for high payload issue, the co-axial propeller based propulsive system is the best alternate, which can be able to provide high thrust with compact size and more stability. Therefore, the study about co-axial propeller and its performance has emerged. Similarly, this work also deals with the comparative investigation about the cumulative thrust force effect on co-axial propeller. Aerodynamic force calculation on the co-axial propeller is executed with the help of standard aerodynamic formulae for validation purposes. The conceptual design of the co-axial propeller is modelled in CATIA. Numerical estimation of aerodynamic forces on UAV's co-axial propeller is analysed with the help of ANSYS Fluent. After the drag comparison, the distances between the propellers in the co-axial set-up are modified for optimization. Finally, the different models undergone comparative numerical simulation and thereby optimization took place.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84764255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal management of the battery is necessary to enhance the performance of the battery module at extreme operating conditions. Battery thermal management systems using phase change material can be used to control the temperature extremity and to achieve uniformity in temperature inside battery module. In this work, the conventional battery layout system is modified to induce the passive cooling with the use of PCM (paraffin wax) which has been placed around the periphery of each cell in the battery pack. Different thickness of PCM layer 2mm, 3mm and 4mm have been taken. This reduces the weight and cost compared to the existing PCM based BTMS. This also ensures improvise in the efficiency of the battery. The battery thermal behaviour is studied using ANSYS for various discharge rate condition (4C, 3C, 2C and 1C) with air assisted cooling system having an air flow rate of 4m/s. From the analysis, it is found that maximum temperature of a battery pack at 4C discharge rate without any BTMS is, about 60C. Elevated temperature of the battery pack covered with a PCM, for same discharge rate with same air flow rate for 2mm is 33.5C and for 3mm it is 34.4C and for 4mm it is 34.07C which falls under the optimal temperature. While adding expanded graphite to the PCM it is found that the temperature reduces to 30C for 2mm thickness PCM.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87115318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
