Taschenbuch. Condizione: Neu. Neuware - Every rocket carries everything it needs to push itself - and that single fact makes propulsion the toughest constraint on almost any space mission.Rocket propulsion sits where thermodynamics, chemistry, fluid mechanics, heat transfer, and flight mechanics meet. Master one thread but stay vague on the rest, and you can plug numbers into equations without ever seeing why a design turns out the way it does. Too many resources deepen the problem, quoting finished results or treating a single subsystem in isolation.>Inside, you will: - Follow first-principles derivations instead of memorising detached formulas- Work examples that carry their units all the way to the answer- Estimate performance with characteristic velocity, thrust coefficient, and specific impulse- Build velocity-increment budgets and weigh staging and mission trade-offs- Compare engine power cycles, cooling methods, turbopumps, and feed systems with confidence- Reinforce every chapter with summaries, practice problems, and worked answer keys- Reach for appendices of constants, propellant properties, key equations, and orbital dataTopics include the reaction principle and the rocket equation; gas dynamics and nozzle design; performance parameters and efficiencies; flight mechanics, staging, and mission budgets; propellant chemistry and combustion; liquid-engine architecture and cycles; thrust chambers, injectors, and cooling; turbopumps; solid motors; hybrid and electric propulsion; heat transfer, materials, and structures; and combustion instability, testing, and system integration. It is written for upper-level undergraduate and graduate engineering students meeting propulsion in depth, and for practicing engineers and researchers who want a reference that derives its results rather than merely stating them. A working knowledge of calculus, differential equations, and introductory thermodynamics and mechanics is assumed; each chapter supplies the rest.

Paperback. Condizione: new. Paperback. The transmission and distribution network carries every kilowatt-hour to the point where it is actually used, and it is the part of the power system that formal training covers least completely. Engineers in this field are served by two kinds of book, and neither is sufficient alone. The academic text derives line equations and load flow with rigour but says almost nothing about conductor selection, sag and tension, ground grid design, cable current rating, or relay coordination. The utility manual supplies procedure in abundance but presents its results as rules to be followed rather than as consequences to be understood. An engineer holding only the first cannot design a feeder. An engineer holding only the second cannot recognise the moment when the rule stops applying, which is exactly the moment when judgement is required. This handbook closes that gap across sixteen chapters, developed in one consistent notation and carried through to the level of a working calculation. Derivations are shown in full, assumptions are stated where they are used, and units are tracked throughout. Concepts are developed once, in the chapter that owns them, so each chapter can be consulted on its own. What you will be able to do: Build the analytical vocabulary the field depends on, including three-phase representation, per-unit modelling, symmetrical components, and sequence networks, developed from first principles.Carry an overhead conductor from thermal rating through ice and wind loading, catenary behaviour, change of state, ruling span, creep, clearance, insulator swing, and right-of-way width.Rate underground circuits properly, treating the thermal circuit, soil resistivity and dry-out, mutual heating, cyclic and emergency ratings, charging current, and sheath bonding.Design a ground grid to a defensible standard, from soil resistivity and tolerable body current through grid resistance, ground potential rise, mesh and step voltages, and transferred potential.Plan a feeder and hold its voltage: load forecasting, load reach, voltage drop, losses, economic conductor selection, capacitors, regulators, and power quality.Calculate faults and coordinate protection across all four fault types, system grounding, time-current characteristics, distance and pilot schemes, and differential protection.Evaluate reliability and change, using standard indices, predictive feeder analysis, asset management, hosting capacity, interconnection, and energy storage.Coverage runs from grid structure and load characterisation through line parameters, overhead and underground construction, insulation coordination, transformers, substations, grounding, distribution planning, voltage regulation, fault analysis, protective relaying, load flow and stability, and reliability and distributed energy resource integration. Worked examples show every material step, graded practice problems close each chapter, and the appendices collect conductor and cable data, standard ratings and insulation levels, unit conversions, and the device number reference used on protection drawings. It is written for practising transmission and distribution engineers, utility planning and protection staff, consulting engineers, technologists entering power system work, and senior undergraduate and graduate students. It assumes introductory circuit analysis and comfort with phasors, but no prior exposure to power systems. The treatment is oriented to Canadian practice, where ice loading is a design case and requirements vary between provinces, while the analytical content remains fully transferable elsewhere. Open this handbook and start building the kind of understanding that lets you not only perform the calculation, but defend the result.

Paperback. Condizione: new. Paperback. Complex systems rarely fail because a calculation was wrong. They fail because two teams held incompatible assumptions about an interface and neither wrote them down. They fail because a requirement was satisfied exactly as written, and the written version was not what anyone needed. They fail because a decision made in the first eight weeks, on very little information, quietly determined an outcome that surfaced three years later. These are failures of relationships, and no single engineering discipline owns them. Most engineers arrive at systems responsibility sideways. They were excellent subsystem engineers, they were handed ownership of the whole, and they found that the skills which earned them the promotion do not automatically extend upward. The available guidance often makes this harder: methods are presented as procedures without the conditions under which they break, and worked examples skip the arithmetic that would have taught something. This handbook was written to close that gap. Seventeen chapters across seven parts, with worked examples that show every step, practice problems with answer keys, three appendices, a glossary and a list of symbols.Methods are presented with their documented failure modes - why a trade study built on multiplied ordinal scores can reverse its ranking when a scale is relabelled, and why a risk matrix built the same way can rate a low-probability catastrophe below a routine annoyance.Worked examples carry their units through every calculation, state assumptions before using them, and show intermediate quantities instead of jumping to a result.Allocate reliability across subsystems, build fault trees and minimal cut sets, and see where redundancy stops helping because of common-cause failure.Construct a verification cross-reference matrix, select verification methods deliberately, size test margin against measurement uncertainty, and judge what must be re-verified after a change.Write requirements that are verifiable, separate derived from allocated, and review a set for ambiguity and completeness.The vocabulary is locked and used consistently, because verification and validation are not interchangeable, a need is not a requirement, and architecture is not design - and each collapse corresponds to a real failure mode.Proportionality is addressed directly: how much process a programme actually warrants, with the honest acknowledgement that this judgement is made badly in both directions.Coverage follows the shape of the work: emergence, boundaries and system context; lifecycle models, stage gates and technical reviews; stakeholder elicitation, operational concepts and measures of effectiveness; requirement quality, traceability, budgets and margin; functional decomposition, states and modes; architecture views, modularity and design structure matrices; interface specification and the two-party ownership problem; model-based practice; trade studies, value functions and sensitivity; model fidelity and uncertainty propagation; the human element; reliability, availability, maintainability and safety; risk, opportunity and management reserve; integration, verification and validation; configuration and data management; technical planning and leading indicators; and transition, support, obsolescence and retirement. It is written for the practicing engineer who has become responsible for a system rather than a component, for graduate students meeting these methods formally in a one- or two-semester sequence, and for the experienced practitioner who needs one specific method on one specific afternoon. It assumes an engineering background - algebra, basic probability, elementary calculus - and no prior systems engineering training.

Paperback. Condizione: new. Paperback. A hydraulic system on a mobile machine is asked to do something no laboratory circuit is ever asked to do. It must start at minus twenty degrees and run at ninety. It must deliver full pressure to a boom while the same pump steers the machine and drives a cooling fan. It must survive vibration, impact, abrasive dust, and an operator who has learned that a function moves faster if the lever is slammed. And it must do all of it for ten thousand hours. Most hydraulics books were not written for that machine. They were written around the stationary industrial circuit, and the physics they teach is identical. What they do not teach is the set of compromises mobile duty forces on the designer and the technician: why a load-sensing margin is set where it is, why a counterbalance valve makes a boom stable in one circuit and unstable in another, why a machine that passed every bench test overheats in August, and why one fault produces different symptoms on an open-centre machine than on a flow-sharing one. Engineers rework circuits that were right in theory and wrong in duty. Technicians replace components in order of cost until the symptom goes away. This handbook was written to close that gap. It develops the fundamentals in enough depth that the later material is derivable rather than memorised, then works outward through components, circuits, whole-machine architectures, thermal behaviour, diagnostics and safety.Trace the efficiency chain from crankshaft to actuator rod, and find where a duty cycle's energy goesCompare open-centre, closed-centre, load-sensing and flow-sharing architectures, and see why a saturated machine behaves differently under pre-compensation than under post-compensationAssign a target cleanliness from the most sensitive component in the circuit, and balance ingression against removalSet a counterbalance valve for stable control of an overrunning load, and predict the back pressure and heat it producesBuild a duty-cycle heat balance, size a cooler and fan drive from it, and judge whether energy recovery repays its costReason from symptom to cause using pressure, flow, case-drain and temperature measurements, rather than replacing parts in order of expenseCompile a stored-energy inventory and specify a de-energisation sequence covering every sourceCoverage runs from fluid properties and viscosity selection, conductors and routing, reservoirs, filtration and contamination control, through pumps, motors and cylinders, pressure and directional control, accumulators, flow control and load-holding, to pump control architectures, hydrostatic propel circuits, electrohydraulic control, thermal management and failure analysis. Four case studies take a tracked excavator, a wheel loader, a telehandler and an agricultural implement from duty cycle through to a drafted circuit and a documentation package. Every chapter opens with learning objectives stating what you should be able to do on finishing it. Derivations are shown in full, worked examples carry their units through every substitution, and graded practice problems close each chapter with answers supplied. Seven appendices, a list of symbols, a glossary and an index put the reference material within reach, including cleanliness targets by component class and a symptom-to-cause troubleshooting quick reference. It is written for the design engineer sizing a system, the field service engineer and technician diagnosing one, and the advanced student who needs the derivations that hold the rest together. Where a design decision is contested in practice, the book gives the trade-off rather than pretending a single answer exists. Begin reasoning from duty cycle to a defensible circuit, and from symptom to cause, with a working reference built around Shipping may be from our UK warehouse or from our Australian or US warehouses, depending on stock availability.…
