The new Holy Grail for aerospace design in the future would have to be shape shifting materials, manufactured memory, and new space-age materials built from the bottom-up at the nano-scale. Currently, scientists are learning great things about Bucky Paper, Carbon Nano-tubes, and Graphene coatings which are only one atom thick. Of course it's not just aerospace design that needs to strengthen its materials and lighten its load, as they could do a great bit of help throughout our transportation sector.

New alternative energy vehicles that weigh a fifth of what cars do today will easily be able to comply with any future miles per gallon mandates, to deal with our nation's oil usage challenges. In fact, General Motors Labs has come up with a new material, which they hope to use in a fuel-cell membrane, that can maintain for her manufactured memory shapes, which will coincide with four different temperatures.

Physics dot Org online newletter describes it as "The material, a perfluorosulphonic acid ionomer (PFSA) called Nafion - a shape memory material," and goes on to state; " These materials can remember shapes set under specific conditions of moisture content, temperature, light, or exposure to a magnetic field." So far this material is made in small film structures, but this makes it a perfect type of material to use in aviation. I propose using it for;

• Aircraft Wings
• Hypersonic Aircraft Intakes
• Helicopter Blades
• Aircraft Windscreens and Windows
• Aircraft Fuel Tanks
• etc.

After all, why let the automotive industry have all the fun, we can use space-age materials for NASA off planet colonies, bridges and roads, homes and buildings, ships and boats, containers and trucks, and even bicycles and golf clubs. Even a teapot which changes shapes makes a lot of sense. Shape shifting materials are the wave of the future, and it appears that General Motors is finally on the leading edge of this technology.

What they have discovered - and what other top universities and research and development companies are currently working on with such materials will surely change the way we live, and General Motors is pretty sure it will change the way we drive. It appears that this nation will be able to meet all of its goals in the future for alternative energy in vehicles, as well as meet all the goals to reduce fossil fuels in our cars. This is definitely a major breakthrough, so please consider it, and all the potential applications.

How Does a Transit-time Ultrasonic Flowmeter Work?

Transit-time meters, as the name implies, measure the difference in travel time between pulses transmitted in the direction of, and against, the flow. This type of meter is also called time of flight and time of travel.

In the example shown in Figure 1, the sonic beam is at a 45º angle, with one transducer located upstream of the other. Each transducer alternately transmits and receives bursts of ultrasonic energy; the difference in the transit times in the upstream vs. the downstream directions (TU - TD) measured over the same path can be used to calculate the flow through the pipe:
V=K*D/Sin2?*1/(To-t)²?T

where:
V= Mean Velocity of flowing fluid
K= Constant
D= i.d. of pipe
?= incident angle of ultrasonic burst waves
To = zero flow transit time
?T = T2-T1
T1 = transit time of burst waves from upstream transmitter to downstream receiver
T2 = transit time of burst waves from downstream transmitter to upstream receiver
t = transit time of burst waves through pipewall and lining

This equation shows that the liquid flow velocity is directly proportional to the measured difference between upstream and downstream transit times. Because the cross-sectional area of the pipe is known, the product of that area and the flow velocity will provide a measure of volumetric flow. Such calculations are easily performed by the microprocessor-based converter. With this type of meter, particles or air bubbles in the flow stream are undesirable because their reflecting qualities interfere with the transmission and receipt of the applied ultrasonic pulses. The liquid, however, must be a reasonable conductor of sonic energy.
Figure 2 shows three placements that can be used for the two transducers. All are identified as single measuring path because the sonic beam follows a single path, and in all three the two transducers are connected by cable to a converter that can output a 4-20 mA DC signal. The selection of one configuration over another is dictated by several factors associated with the installation, including pipe size, space available for mounting the transducers, condition of the inside pipe walls, type of lining, and nature of the flowing liquid.
The Z configuration places the transducers on opposite sides of the pipe, one downstream of the other. Generally, the distance downstream is ~D/2, where D = pipe diameter. The converter uses specific data on piping parameters to compute the optimum distance. The Z method is recommended for use only in adverse conditions such as where space is limited, the fluid has high turbidity (e.g., sewage), there is a mortar lining, and when the pipe is old and a thick scale has built up on the inside wall that tends to weaken the received signals. It is not recommended for smaller pipes, where its measuring accuracy tends to degrade.
In most installations, the V method is recommended, with the two transducers on the same side of the pipe about a pipe diameter apart. The rail attachment that can be clamped on the pipe facilitates sliding the transducers horizontally along the pipe and positioning them the calculated distance apart.
The W method should be considered on pipe 1½ in. down to ½ in. dia. Its main limitation is a possible deterioration in accuracy due to buildup of scale or deposits on the pipe wall-note that the sonic signal must bounce off the wall three times. Turbidity of the liquid also could be harmful since the signal has a longer distance to travel.
