1. Aerodynamic Forces
Abstract
There are numerous forces acting on objects in everyday life.
For example, which forces are at play on a boat floating on water?
What about a rock on an incline that doesn’t roll down the slope?
Which of these forces operate on an aircraft in flight? Are there any others?
Discuss the preceding introductory questions and then fill in the table below.
John D. Nixon, Joseph Michaels
2. Wings and Airfoils
Abstract
Match the letters in the following diagrams with the words provided.
John D. Nixon, Joseph Michaels
3. Aircraft Motion
Abstract
There are three main movements of an airplane each acting along one of the three-dimensional axes: pitch, roll and yaw. Each movement requires the use of certain parts of an aircraft.
John D. Nixon, Joseph Michaels
4. Propulsion Systems
Abstract
There are four main types of propulsion systems used in planes and they include: propeller propulsion, gas turbine propulsion, ramjet propulsion and rocket propulsion.

5. Green Aviation
Abstract
Airplane manufacturers have consistently designed and implemented a host of innovations since the advent of commercial air travel in the 1960s to lower fuel consumption on airplanes and thereby reduce harmful exhaust emissions. While this process has been driven by a desire on the part of airlines to lower costs, growing environmental awareness and concerns as well as demands from private citizens and passengers have led governments to agree to lower their countries’ respective carbon footprints, which in turn has put pressure on the aviation industry to innovate further.

6. Helicopters
Abstract
A helicopter is equipped with one or more power-driven rotors (horizontal propellers) in lieu of fixed wings. It is able to take off and land vertically, to move in any direction, or to remain stationary in the air. The lift developed by a conventional aircraft wing depends on two factors: the angle of attack of the wing (Figure 6.1) and the velocity of the air in relation to the wing. To obtain the necessary lift, the aircraft must have a forward movement.

7. The Future of NASA
Abstract
NASA’s Vision

8. An Introduction to Chemical, Electric, and Reusable Propulsion Systems
Abstract
Rockets have existed for centuries. While it is unclear when the first rockets flew, it is known that they were standard issue for the Chinese army by the mid-14th century. Until the early 20th century, however, rocket motors were never more than a few percent efficient.
John D. Nixon, Joseph Michaels
9. Orbits
Abstract
When a satellite reaches exactly 42,164 kilometers from the center of the Earth (about 36,000 kilometers from Earth’s surface), it enters a sort of “sweet spot” in which its orbit matches Earth’s rotation. Because the satellite orbits at the same speed that the Earth is turning, the satellite seems to stay in place over a single longitude, though it may drift north to south. This special, high Earth orbit is called geosynchronous.

10. Commercial Opportunities in Satellite Technology
Abstract
Alongside their essential function in keeping our global society ticking, satellites also represent a paradigm shift in humankind’s relationship with space. Our motivation for reaching the great beyond arose out of scientific curiosity and the urge to explore our surroundings. This motivation still exists since we have only just begun to branch out beyond our terrestrial roots.

11. Space Debris and Its Solutions
Abstract
Humans tend to leave behind a mess wherever they go. Space is no different. One grave issue facing our use of outer space in the future is the accumulation of space debris. Due to its high kinetic energy, space debris poses a risk for both technology and humans in space.
John D. Nixon, Joseph Michaels
12. The International Space Station and Perseverance
Abstract
The ISS supports a variety of pure and applied research for the US and its international partners and plays a critical role in supporting the Vision for Space Exploration. The ISS provides a unique, continuously operating capability: to develop medical countermeasures for long-term human space travel, to develop and test technologies and engineering solutions in support of exploration, and to provide ongoing practical experience living and working in space.
John D. Nixon, Joseph Michaels
13. Space Elevators
Abstract
The children’s story “Jack and the Beanstalk” could soon move from the realm of a fairy tale to practical reality if work on the project of a space elevator, now at an advanced engineering stage, receives the go-ahead for construction.
