Standard
AS6502
This SAE Aerospace Standard (AS) provides classical propulsion system performance parameter names for aircraft propulsion systems and their derivatives, and describes the logical framework by which new names can be constructed. The contents of this document were, originally, a subset of AS755E. Due to the growing complexity of station numbering schemes described in AS755, and a desire to expand the original document's nomenclature section to include a fuller representation of "classical" (legacy use) names, a decision was made to separate its "station numbering" and "nomenclature" content into two separate documents. This document, then, was created using the "nomenclature" half of AS755E. Both documents will continue to be improved and revised as industry needs dictate. The parameter naming conventions presented herein are for use in all communications concerning propulsion system performance such as computer programs, data reduction, design activities, and published documents.

Abstract The death toll due to traffic accidents in India is on a rise, according to the latest Road Transport ministry report, a total of 4.97 lakh road accident was reported in 2011. Though compared to 2010, the accidents have gone down by 1,945, the number of deaths at 1,42,485 has increased by over 7,000.[1] This paper proposes a design of an Emergency Intimation System (EIS) tailored to fit for Indian consumer needs and available infrastructure. EIS is an emergency alert technology devised to assist drivers and passenger in an event of vehicle crash. Majority of deaths are caused by slow accident response time. EIS is aimed to lower this response time and ensure that the required rescue and medical services are made available in time. This device employed to make this emergency alerts will be fitted into the vehicle Electrical and Electronics (E/E) architecture and will have interfaces with crash sensor network, CAN network and GSM etc.

Abstract In order to minimize the development and production costs in the automotive industry, despite steadily increasing variety of models and applications offered by the OEMs, the pressure on standardization of components and production processes is increasing continuously. As a direct consequence, modular engine families are already established with high degrees of common parts and kits as well as standardized interfaces for all vehicle platforms by most manufacturers these days. At the same time, the world adopted and announced massive legal demands concerning the reduction of CO2 emissions for the entire vehicle fleet. In addition to the optimization of the combustion process, the exhaust gas aftertreatment and thermal management, the use of improved and more resilient materials for higher reduction of mechanical friction leads to a significant amount of the realized lowering in fuel consumption respective CO2 emissions.

Abstract The present paper is an introduction to a novel rotary valve engine design addressing the major downfalls of past rotary valves applications while permitting the typical advantages of the rotary valves. Advantages of the solution are the nearly optimal gas exchange, mixture formation, ignition and combustion evolution thanks to the large gas exchange areas from the two horizontal valves per engine cylinder, the good shape of the combustion chamber, the opportunity to place a direct fuel injector and a spark or jet ignition device at the centre of the chamber. The novel engine design also permits higher speed of rotation not having reciprocating poppet valves and the reduced friction losses of the rotating only distribution. This translates in better volumetric efficiencies, combustion rates and brake mean effective pressures for improved power density and fuel efficiency. Additional advantages are the reduced weight and the better packaging.

Abstract Light weighting is the Current trends in automotive to achieve better fuel economy which helps for meeting fuel economy standards & to offset the higher fuel prices. Thus there is a need to develop composite running board which is light weight & structurally sound enough to meet the performance. The present paper provides a composite running board assembly for an automobile. The running board assembly includes a board, an insert body and a plurality of brackets. Upon stepping of a passenger on the board, the board transfers load on the insert body which subsequently transfers the load to the plurality of brackets thus facilitating even distribution of the load on the automobile body. This paper also put lights on the use of improved TRIZ application - an approach to inventive problem solving for designing highly affordable & light weight running board. The cost & weight reduction achieved with innovative design is about 40 % & 35 % comparing to existing cost & weight.

Abstract Every organization needs to effectively manage its data collection and analysis process in order to efficiently collaborate on a global scale. This paper describes a model for standardizing the data collection and analysis process and specifically deals with two challenges in this regard: 1) A method for standardization of the nomenclature of different physical parameters measured during a typical engine test. This is essential for processing data from facilities spread across the globe to run them through a standard set of calculations. The process of storing and performing a given set of complex processes on the data while allowing analysts to view the steps of the processing in a transparent intuitive manner is also described in the paper. 2) Building on the first point, the paper also describes a process for performing a standard set of data quality checks on data as it is being collected. This allows for detection of issues in the data on a real-time basis.

Abstract Typical software that is used for engine test result analysis include spreadsheet (MS Excel) and statistical software (Minitab, MS Excel), data modelling applications (MS Excel, Matlab), and post processing tools for plots, tables etc. Open source software has come a long way since its inception, and is now at a stage where it can provide a suitable alternative to many commercial software packages for data analysis. The paper will describe the areas of concern and the inherent benefits to using open source software. It evaluates the feasibility of incorporating these open source tools into data analysis packages for Engine Development by breaking down the process of data analysis into specific software requirements and then evaluating each of the open-source alternatives against these requirements. The paper will conclude by describing a practical strategy when converting an existing data analysis process over to its open-source equivalent.

Abstract Access to Knowledge resources around the world demands special skills and calls for judicious investments. Networking is an effective tool and building networks through consortia approach is dire need of the hour. Although this approach has been used in academia, its application in industry, especially among corporate entities, is rare. This paper describes in brief an optimised way to access databases, subscriptions & memberships of different technical societies from global platforms for research & progress of Indian automotive industry. It is imperative for Indian automotive industry to enhance and strengthen its knowledge resource base, particularly in product development and manufacturing domains. This will enable the industry to achieve its mission -“AMP-2016” of becoming a hub for global auto industry. Instead of “compete and grow,” an approach of “collaborate and grow” is thought of.

Abstract In this study, an alternate way of development and implementation of control strategy for torque split of a Hybrid Electric Vehicle (HEV) is proposed. The control strategy evaluates each and every operating point for Internal Combustion Engine (ICE) and electric motor-generator (E-machine) corresponding to all possible torque split combinations at present time instant and finally chooses one combination with the least cost function, which is estimated by converting electrical energy into equivalent fuel consumption[2]. Henceforth, the control strategy is able to perform real time iterations to choose the E-machine and ICE torque combinations with least effective fuel consumption also referred herein to as the optimal operating points. As a result, by running the vehicle at optimal operating points, overall fuel consumption over the complete drive cycle is reduced.

Abstract In current scenario importance of fuel efficient vehicles, lesser emissions & energy efficiency are the major considerations for any vehicle manufacturer. To meet these expectations vehicle manufacturer are exploring alternate powertrains to reduce emissions and produce better fuel efficient vehicles. For any vehicle manufacturer component cost, weight and package volume are the major driving factors for success. This is even true for latest upcoming hybrid and electric vehicles as well. To gain advantage and introduce products faster, OEMs are inclined to electrify their existing platforms to compete with other manufacturers. To convert existing vehicles into hybrid vehicles, all the major components like e machine, High voltage battery, power electronics etc. needs to be carefully packaged along with existing components in the same package space.

Abstract A feature of the present state of the Russian agricultural industry is that productive resources (tractor pool, arable land area and number of workers involved) are diminishing and the reduction does not have a quantified value. In the prevailing conditions of limited resources, agricultural enterprises are forced to operate tractors beyond their amortization periods on a massive scale, which results in an unpredictable service life. This situation calls for an assessment of the optimal composition of the tractor pool in terms of number and age. By way of a solution to this problem, the given article presents a methodological approach as to the analysis of two opposing factors.

Abstract In the current competitive automobile market, with growing knowledge and concern for occupant and vulnerable road user safety, design & engineering of passenger cars in stipulated time is a challenge. As front styling is a crucial factor, early involvement of Computer Aided Engineering (CAE) through front loading helps reduce the product development time considerably with a pedestrian friendly engineered design. The present paper explains how initial inputs are given to styling & engineering teams during early stages of product development where availability of Computer Aided Design (CAD) data is minimal. Critical load paths were identified and shape of the front end was modified accordingly. Various locations of hinge mechanism were evaluated to reduce the severity of injury in the head impact zone. Sufficient gaps between the exterior surfaces and interior hard points were worked upon to reduce the impact values.
