Current technologies are graphene, propylene glycol, gyroscope technology & Sorbothane.
Graphene:
- Thin layer of pure carbon
- Atoms in honeycomb form
- Stack a few layers of graphene to have graphite
- Currently the strongest material on earth
- 1 sheet can support an elephant
- Scientists had to separate graphite layer by layer until 1 layer remained to make graphene
- It's 200 times stronger than steel and 1,000,000 thinner than human hair
Propylene glycol:- Form of mineral oil
- An alcohol produced by fermentation of yeast and carbohydrates
- Used in engine coolants and antifreeze, airplane de-icing, polyurethane cushions, paints, enamels and varnishes
- Cushions are made of polyurethane for comfort
- Propylene glycol gel doesn't freeze, not even at high altitude
Gyroscopes:- Devices that use gravity to orient themselves in one continual direction
- Made of a freely-rotating disk called a rotor sitting on top of a spinning axis in the middle of a bigger and more stable wheel
- Need airline seat to point in one direction for safety and comfort
Sorbothane:
- The underside of the SSS 1.0 can be coated in Sorbothane
- Also known as a viscoelastic urethane polymer, which absorbs 94.7% of shock
- Sorbothane acts like a liquid when hitting something, even though it is a solid when at rest
- Sorbothane is a thermoset, polyether-based polyurethane material
- Can dampen vibrations
- Can work when the temperature is -29 ℃.
| | The past holds ejection seats and low-tech gyroscopes, as well as the structure of graphene.
The Creation of Graphene: - Began as block of graphite
- The block was cut into very thin layers
- The scientists realized that they had found graphene
- Discovered by V. Kohlschütter and P. Haenni
Ejection seat: - Saved over 7,500 lives
- Used to have a handle at top
- Handle moved to bottom for the ability to reach it more easily
- Fitted with a parachute
- First ejection seat was demonstrated in a jet known as the Meteor
Low-tech gyroscopes: - The first gyroscope was the well-known toy called the top
- Gyroscopes have a rudder that spins
- Gyroscope technology has been used for many things
Sorbothane: - Was made using polyol and isocyanate
- Designed to absorb shock
- Deformed easily
- Recovered slowly
- Acted like a liquid when hitting something
- Acted as a solid otherwise
- Invented by Dr. Maurice Hiles
