Most recent or all developments in the field of small UAV’s seem to use Quadcopters. It’s a valued commenting that a quadcopter is a smaller amount stable than a similar regular chopper and is additionally less economical. A Quadcopter UAV’s with four propellers is always a major concern to the society when brings to its stability as its major factor. To design and analyze the use of one propeller monocopter is the main objective of this paper. Wacky Whirler technology used here to demonstrate the passage of the monocopter. It is a single propeller powered with a coreless motor which is a modern enhancement in the UAV. It is based on the All Rotating monocopter theory. In the proposed system, controller based on IOT can be used which will be helpful in monitoring and processing the microdrone status.
In sheet metal painting for various applications like Tractor, Automobile, most attractive coating is metallic paints and it is widely applied using 3 coats 2 bake or 3 coat 1 bake technology. Both options, results in high energy consumption, higher production throughput time & lower productivity in manufacturing process. During various brainstorming & sustainable initiatives, paint application process was identified for alternative thinking to reduce burden on environment & save energy. Various other industry benchmarking & field performance requirement studies helped us identify the critical to quality parameters. We worked jointly with supplier to develop mono-coat system without compromising the performance & aesthetical properties. This results in achieving better productivity, elimination of two paint layers, substantial reduction in volatile organic content, elimination of one baking cycle and energy saving.
In this paper, mold in color diamond white ASA material has been explored for front bumper grill, fender arch extension and hinge cover applications. Other than aesthetic requirements, these parts have precise fitment requirement under sun load condition in real world usage profile. Structural durability of the design was validated by virtual engineering. Part design and material combinations with better tooling design iterations were analysed by using mold flow analysis. Complete product performances were validated for predefined key test metrics such as structural durability, thermal aging, cold impact, scratch resistance, and weathering criteria. This part met required specification. This mold in color ASA material-based parts has various benefits such as environmentally friendly manufacturing by eliminating environmental issues of coating, easily recycled, and faster part production because intended color achieved in one step during molding.
The need for dedicated development of indigenous electric power-train is becoming much essential in the recent times with upcoming trends and policies. Hence, The validation and optimization of the newly developed electric power-train becomes much crucial in order to ensure smooth real world operation. This can be only possible in E-motor test benches with dedicated equipment for thorough evaluation. Also, there are no practical limitations to check the peak characteristics in a controlled laboratory environment. Initially, the motor is setup by mechanically coupling with the dynamo-meter and the controller in the open loop method with constant parameters to check steady state operability without load or external parameters that affect the torque production and speed of the drive. Then progresses to closed loop method incorporating the feedback control and external parameters including torque loading at the shaft from the dynamo-meter.
Title Development of a Graphical User Interface (GUI) Based Tool for Vehicle Dynamics Evaluation Authors Mr. Shubham Kedia, Dr. Divyanshu Joshi, Dr. Muthiah Saravanan Mahindra Research Valley, Mahindra & Mahindra, Chennai Objective Objective metrics for evaluation of major vehicle dynamics performance attributes i.e. ride, handling and steering are required to compare, validate and optimize dynamic behavior of vehicles. Some of these objective metrics are recommended and defined by ISO and SAE, which involve data processing, statistical analysis and complex mathematical operations on acquired data, through simulations or experimental testing. Due to the complexity of operations and volume of data, evaluation is often time consuming and tedious. Process automation using existing tools such as MS Excel, nCode, Siemens LMS, etc. includes several limitations and challenges, which make it cumbersome to implement.
The certification of transport category cabin interiors requires a thorough understanding of Part 25 Transport Category aircraft cabin interior safety and crashworthiness regulations and compliance requirements. Regardless of whether it is a simple modification, a specialized completion (VIP or VVIP) or airline passenger configuration, engineers, designers, and airworthiness personnel must understand and adhere to these requirements. This two day seminar will begin with a discussion of Commercial off the Shelf (COTS) test requirements.
The development of Autonomous Vehicles (AV) has become a popular subject in academia and industry. Companies and cities are quickly realizing the opportunities that AVs can generate from Mobility as a Service to traffic safety. The challenges for the infrastructure to incorporate AVs as a viable transportation source are immense, beginning with an outdated infrastructure. Historically, the transportation infrastructure has been fraught with challenges from underfunding, economics, and misappropriations. With the current infrastructure unable to support many of the services required by a fully connected network, a transformation will be necessary to meet growing mobility needs. The role of accelerating technology in data centers are key for production operations among industry leaders such as Amazon and Microsoft.
In recent decades, fuel economy has become a key indicator of an automaker social responsibility and a market differentiation factor, and ultimately it is regulated by government agencies such as EPA through CO2 emissions compliance tests. The light pick-up truck and SUV production share has been increasing in the last few years, being the 4-wheel drive capability one of the main features that the customers look for. Within the 4-wheel drive system, the transfer case has a significant impact to both torque transfer efficiency and parasitic losses. The scope of this paper is to better understand the parasitic losses of a transfer case by the quantification of its individual drag losses by component. At product development phase, one measurement of interest is the system level spin loss which has a target value defined by the automakers, and contribution by component is often neglected if the system has the expected performance.
Despite the advantages of electronic flight bags (EFB), passenger entertainment and email access during flights, and the ability to access aircraft repair manuals electronically, computer interconnectivity throughout aviation has opened the aviation sector to cyber-attacks that could impact flights, data, and safety. This two-day seminar is intended to introduce aviation professionals to the need to implement cyber security throughout commercial aviation including the supply chain.
ARP4754A substantially revises the industry guidance for the development of aircraft and aircraft systems while taking into account the overall aircraft operating environment and functions. This development process includes validation of requirements and verification of the design implementation for certification and product assurance. ARP4754A provides the practices for showing compliance with regulations and serves to assist companies in developing and meeting its own internal standards though application of the described guidelines.
The quality of production is defined by the actual deviations from the requirements stated in design and technological documentation including drawings. In this article the problem of ensuring steady decrease in quantity of deviations from these requirements by production is considered. Carrying out preventive actions, in combination with control of time and costs of correction of discrepancies of such decrease it is possible to achieve. For the solution of an objective the method of the modified FMEA using parameters and levels of ranging as elements of operation of technological process where at a design stage of a product are set structure, is offered and are adjusted on the basis of feedback of production and operation. Such statement of a problem demands automation of collecting and data processing which can be used for creation of the knowledge base necessary for management of productions.
