There is an ever-increasing need to understand turbulent and multiphase combus-
tion due to their broad application in energy, environment, propulsion, transporta-
tion, industrial safety, and nanotechnology. More engineers and scientists with
skills in these areas are needed to solve many multifaceted problems. Turbulence
itself is one of the most complex problems the scientific community faces. Its
complexity increases with chemical reactions and even more in the presence of
NASA’s budget for fiscal year 2003 included funds to begin the Nuclear Systems Initiative focused on
research into and development of enhanced capabilities in the general areas of spacecraft power and propulsion
Throughout this report, we use the term “WT/PT facilities” to mean wind tunnel facilities and propulsion test facilities, that is, the type of NASA facilities we assessed. Since individual facilities within this designation can be either wind tunnel facilities, propulsion test facilities, or both, “WT/PT facilities” serves as a generic term to encompass them all. That being said, when a specific facility is talked about, for clarity, we refer to it as a proper
(BQ) Part 2 book "Aerodynamics for engineering students" has contents: Compressible flow, airfoils and wings in compressible flow, viscous flow and boundary layers, flow control and wing design, propulsion devices.
Xử lý ảnh số có nhiều ứng dụng thực tế. Một trong những ứng dụng sớm nhất là xử lý ảnh từ nhiệm vụ Ranger 7 tại phòng thí nghiệm Jet Propulsion vào những năm đầu của thập kỉ 60. Hệ thống chụp hình gắn trên tàu vũ trụ có một số hạn chế về kích thước và trọng lượng..
The present “Solar Energy” science book hopefully opens a series of other first-hand texts in new technologies with practical impact and subsequent interest. They might include the ecological combustion of fossil fuels, space technology in the benefit of local and remote communities, new trends in the development of secure Internet Communications on an interplanetary scale, new breakthroughs in the propulsion technology and others.
The Deep Space Communications and Navigation Systems Center of
Excellence (DESCANSO) was established in 1998 by the National Aeronautics
and Space Administration (NASA) at the California Institute of Technology’s
Jet Propulsion Laboratory (JPL). DESCANSO is chartered to harness and
promote excellence and innovation to meet the communications and navigation
needs of future deep-space exploration.
The size and principal
characteristics of a new ship are determined primarily
by its mission or intended service. In addition to
basic functional considerations, there are requirements
such as stability, low resistance, high propulsive efficiency,
and navigational limitations on draft or beam, all
of which influence the choice of dimensions and form.
Within these and other basic constraints, the ship’s structure
must be designed to sustain all of the loads expected
to arise in its seagoing environment.
Xử lý ảnh số có nhiều ứng dụng trong thực tế. Một trong những ứng dụng sớm nhất là xử lý ảnh từ nhiệm vụ Ranger 7 tại phòng thí nghiệm Jet Propulsion vào những năm đầu của thập kỷ 60. Hệ thống chụp hình gắn trên tàu vũ trụ có một số hạn chế về kích thước và trọng lượng, do đó ảnh nhận được bị giảm chất lượng như mờ, méo hình học và nhiễu nền
The permanent-magnet synchronous machine (PMSM) drive has emerged as a top competitor for a full range of motion control applications [1–3]. For example, the PMSM is widely used in machine tools, robotics, actuators, and is being considered in high-power applications such as vehicular propulsion and industrial drives. It is also becoming viable for commercial/residential applications. The PMSM is known for having high efﬁciency, low torque ripple, superior dynamic performance, and high power density.
Vehicles that utilize more than one energy source for propulsion are usually termed hybrid vehicles. Although the onboard energy storage system (ESS) may be a ﬂywheel or a hydraulic accumulator, most hybrid vehicles use chemical batteries or capacitors and are termed hybrid-electric vehicles. Fuel cells (FCs) may be used in hybrid-electric vehicles as primary power sources instead of conventional internal combustion engines (ICEs). In this article, ICE–battery hybrid transit buses are discussed speciﬁcally and contrasted with conventional drive buses. ...
The recent fuel cell (FC) development worldwide has always been accompanied by a number of studies and projects investigating the applications of FCs onboard ships. Almost all possible FC types and different fuels such as hydrogen, natural gas (liqueﬁed or pressurized), liqueﬁed pressurized gas (LPG), methanol, and maritime diesel have been considered. These applications of FCs are still mainly focused on onboard power generation (OPU) and propulsion.
