ABSTRACT Thrust & Torque Calculations for MOV’s using Microsoft Office Products Prepared by Michael C. Richard Teledyne Brown Engineering Desktop computing using Microsoft Office products have changed the way that engineering calculations are performed. But, is the change for the better or the worse? Engineering Managers are faced with the task of “computerizing” engineering calculations all the time. This paper presents some guidance on how to choose the method that best suits your calculation needs. Specifically, three methods of calculating thrust and torque for MOV’s will be presented. The three methods consist of an Excel model, an Access model, and a final model which uses Microsoft Visual Basic combined with Access (Microsoft Jet) …show more content…
The software validation process begins when the coding process has been completed. • Maintenance: Provide support for completed products until the product is retired. You may be thinking to yourself, "I 'm only writing a simple Excel spreadsheet, so this doesn 't apply to me." The purpose of presenting a software development model is to demonstrate that coding is only a piece of the overall development process and that it is not the first piece that should be done. The can be restated as follows:

The generic software development model presented was illustrated for commercial grade software. The Testing phase of the software development cycle is a recommended practice for commercial grade software but does not necessarily have to be performed. The incentive for performing Verification and Validation testing is economics. Untested software will contain defects and may not meet the specification of the customer. Unhappy customers and high maintenance costs usually justify performing some amount of testing during the development
Torque is a measure that shows how much of a force acting on an object causes it to rotate. It is the product of the acting force on an object and its distance from the fulcrum (lever arm)
The Verification and Validation, or V-model, Software Development Paradigm will be used to define the development life cycle of the software product. This paradigm was chosen because it allows us to test the software during each stage of the project in an inverse way. Also, because the validation and verification of
For the system, which should never be failed, the reliability test of the software should be done. For this, the black box and white box testing should be done on the software. After the successful development of the software, a beta version should be released. The errors and bugs related to the security and functional requirements can be find out in an easy manner.
The main purpose of this paper is to have a brief analysis and evaluation on the project provided by Road King Trucks Company. Six main problems offered are the main topics in this paper. After evaluation, a recommendation will put out to choose the right engine and on the project.

oxygen fuel.The two liquids were delivered to the thrust chamber by two rotary pumps, driven by a steam turbine. The steam turbine operated at 5,000 rpm on two auxiliary fuels, namely hydrogen peroxide (80 %) and a mixture of 66% sodium permanganate with water 33%. This system generated about 55,000 lbs (24,947 kg) of thrust at the start, which increased to 160,000 lbs (72,574 kg) when the maximum speed was reached (V2ROCKET.COM).
A Raspberry Pi computer was set up to the Python software and, within testing, proved to not only be noticeably slower but also be extremely less accurate, as shown in Figure 9. This data was collected in a tool that was created to measure the exact angle of motor turns at the same settings, shown in Figure 10. This data, along with previous experience, lead to the chosen programming language to be C.
Eureka is a new simulation tool, for the analysis and optimization of the milling and turning machines. It has the graphical interface and APIs compatible with many programming languages including C++, VB, .NET, VBScript and Delphi.
The analysis of the performance of the car under test was completed using AVL Cruise software. Various Graphs are obtained so that the actual performance of the car can be determined. Graph 1 (Abundance) prominently shows the torque of the engine at the respective engine speed along with the specific fuel consumption at that speed. Approximately 230Nm is the maximum torque that can be obtained at 4200 rpm, trailed by decrease in torque for the remaining speed. A cycle run was conducted for three different periods of cycle in which the vehicle was accelerated then hold and decelerated for certain time depending upon the requirement of cycle. Graph 2-A shows the change in velocity upon change in acceleration for three different cycle times. Also the shift of gears during the period can be observed. Graph 2-B illustrates consumption of the fuel during the three different stages. It can be noted that when the velocity was about 50 km/h the fuel consumption was about 5.0 l/h. Also it significantly notifies that during idling the fuel consumption is 1.6 l/h. In this Graph it can be inferred that the maximum operating pressure is 12 Bar for a speed of 4200rpm. Maximum fuel is consumed during the start of the engine at 0.5 bar, fuel consumption gradually decreases with increase in engine speed. Graph 3 speaks about the maximum operating pressure is 12 Bar for a speed of 4200rpm. Maximum fuel is consumed during the start of the engine at 0.5 bar and also between 0 bar and 1.6 bar at
Populated in Table 1 are the discrete power and torque values in both English and SI units at a given engine operating point. Figure 1, as shown below, provides a cogent representation of the trends that the power and torque
In recent times, CFD analysis, with the advent of computer architectures with superfast processing capabilities are rapidly emerging as an alternative to wind tunnel tests. In vehicles body development, reducing of drag is essential for improving fuel consumption as well as protect the global environment and the aerodynamics refined body is also aesthetically attractive, it will appeal to the customers. In this papers the process taken to optimize the shape of a vehicles . The Autodesk CFD program was used to iterate toward a converged solution with the goal of obtaining a better flow around the vehicle. The results are analyzed and only the drag force is compared with a recognized journal to validate the results. These practices were detailed in hopes that further research would use the ground work laid out in this paper to redesign existing vehicles in order to improve handling and increasing fuel efficiency.
The aim of this paper is to study various parts of MAV Sys, their probable applications in mil svy and to recommend them for use in mil svy
With an aspiration to explore more in various aspects of Mechanical Engineering, I took elective courses in Computational Fluid Dynamics, Combustion Engineering, I. C. Engines, Finite Element Methods and Design of Fluid Machinery. In later, I opted for a course project on design of turbine blade profiles to gain a deeper understanding of the subject. I investigated flow angles for various flows like free & forced vortex, power blading to design the 3D blade profiles in SolidWorks.
In software development, there are various types of methods that developers follow in order to produce valuable software. From the many types of methods that exist today, the industry standard that is mostly followed today is the software development lifecycle (SDLC). The SDLC is a process that software development companies utilize in order to design, develop and test software during production. Within the SDLC, there are different test models that developers can utilize based on their business and development requirements. Currently today, the most common models include the waterfall, iterative, spiral and V-model. Regardless of the model that a developer decides to utilize, all the phases will be the same, which would begin with the first step and that is the requirement gathering and analysis phase.
