für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Indian economy though one of the fastest growing economies in the world, a large percentage of Indian population lives in rural areas and depends on agrarian economy. Rural India needs affordable and simple transport system for small scale (125 kg) and short distance (up to 10kms) transportation of fodder, fertilizers, seeds and many house hold items. Motorcycles (two-wheelers) are a popular mode of transport in rural areas. Commercial designs of motorcycles have a limitation to use them for small scale and short distance transport of goods. A trailer to a motorcycle would solve such transport problems partially and hence the present project entitled Design and development of motorcycle trailer for rural India was undertaken.A trailer to a motorcycle which can carry up to 125 kgs of weight was conceptualized, designed and developed. A final concept trailer was chosen based on customer s selection among a number of concepts generated.. Fabrication of the trailer was done as per the manufacturing drawings. The trailer was attached to the motorcycle and its capability for short distance transport in rural areas, its maneuverability and stability were subjectively demonstrated. ····· 1036199864
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The two of the largest developments in the 20th century have been the invention of spacecraft, and the invention of nuclear power as a source of long lasting energy. Now, both technological fields have grown immensely to structure the technology of our world. These two fields are intertwined, as the future of space exploration depends on the availability of nuclear power. One of the most important requirements of a space flight mission is to be able to fly to furthest reaches of the universe. In fact, flying anywhere in our Solar System besides the moon will pose a considerable challenge as the distances that need to be travelled are great. The various means of chemical propulsion in spacecraft do not have the necessary high specific impulse and velocity to reach these long distances. But, with the availability of nuclear power, spacecrafts will have the thrust and the necessary power for exploration of interstellar distances. Nuclear propulsion poses the way for exploring our solar system and it provides the means for interstellar exploration. You can find contemporary techniques of nuclear space propulsion in this book and advanced futuristic nuclear space propulsion methods. ····· 1036199770

····· lezzter Preis 44.10€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Recently, continuously variable transmission (CVT) has been much more applied in vehicles as it has several advantages such as smoothly gear changing and allowing engine operate at optimum speed. However, there are some important drawbacks which are low efficiency power transmission, especially at low speed (high torque) condition, limited belt torque capacity, and narrow overall gear ratio range, with which the CVT is limited to use in only small vehicles. To overcome these weak points and simultaneously keep the advantages of CVT, a planetary gear train (PGT) and a step gear box are implemented to the traditional CVT system called continuously variable power split transmission (CVPST) with step gear box system. The power from the engine will be separated into two ways PGT and CVT. As the higher efficiency of PGT than CVT, the overall system efficiency will increase. Also, because only a part of the total power will go through the CVT set, the torque capacity of the overall system can be extended. The additional step gear box is used to enhance the overall gear ratio range. By simulation, the fuel economy and 0-60 time performance of both transmissions can be compared. ····· 1036199482

In such application, this book relates to parametric study of the dynamic characteristics of laminated composite structures. The elastic properties of composite materials depend on diverse factors like the configuration of the laminates, constituent materials used, production method adopted etc.. Hence, it is generally impossible to find these properties in standard tables or databases. The determination of material parameters of the complex materials, such as fiber reinforced composites, present serious difficulties when applying traditional test methods. To overcome these difficulties, the mentioned method, viz., Genetic Algorithm (GA) and Simulated Annealing (SA), have been used to provide additional techniques of evaluating material properties of composite structures from the measured natural frequencies. ····· 1036199284

The different ways of determining whether the car is oversteering or understeering is found by setting up Math Channels. The operation of the onboard logger in preparation to record the car s track test data is discussed after its setup that involved the calibration & verification of several sensors. Once the track test was conducted, the results are analysed by data interpretation techniques needed in identifying if the car is oversteering or understeering by noticing certain traces on Motec I2 Pro from conducted track tests data.

To understand and avoid the dangers related to rotor icing, test facilities such as the NASA Glenn Icing Research Tunnel have been developed. Due to the confined test section size of most current icing test facilities, an icing test on a full-chord helicopter rotor blade is not possible. To fulfill the research need of a novel full-scale-chord rotor icing test facility, the Adverse Environment Rotor Test Stand (AERTS) was designed and constructed at the Vertical Lift Research Center of Excellence, at the Pennsylvania State University. This book gives a comprehensive review of the current aircraft icing research. Ice accretion experiments were conducted to validate ice shape reproduction capabilities of this facility. Classical ice scaling methods were introduced and implemented to ensure experimental ice shape reproduction for varying chord-size blades. The validity of applying scaling laws to low-thrusting rotors was demonstrated. The comprehensive aircraft icing database provided in this book can be applied widely to the aircraft design and testing procedures. ····· 1036192534· 1 ·· 2 ·· 3 ·· 4 ·· 5 ·· 6 ·· 7 ·· 8 ·· 9 ·
