Exercise 1 involves downloading the software to allow the Raspberry Pi to function

Objective: Why?

Ion Thruster is one of the most efficient thrusting mechanism we yet developed. Due to its high fuel efficiency, ion thruster was able to achieve a record of 48000 hours of operation without stopping . ( Experiemnt of NASA's Evolutionary Xenon Thruster). However ion thruster is unusable inside atmosphere due to its weak output. ( About 20~250 mN) . Despite this weakness, ion thruster will be major type of thrusting mechanism in future. In order to do this, ion thruster need to be much stronger than now.

Background: Who? Where?

Targeted goal is to create ion thruster that much smaller and efficient while maintain similar performance. (This will be proportional since actual ion thruster is not a small object. ) . To accomplish this task , we need to find light weighted, strong electric and magnetic field generator.

Methodology: How? When?

Speed of ion ejected from ion thruster is very fast, but due to its light weight, it doesn't give much propulsion. Solution could be following

1. Much dense ionized propellant. ( Plasma can be fasten by magnetic field. Maybe a tokamak could help. )

2. stronger electric field. ( Was thinking using tesla coil, but only high frequency won't effectively work to ionize xenon or hydrogen. ) ( was thinking using ozone was propellant due to easy access to oxygen in atmosphere, but ozone is toxic and very strong oxidation agent. ) ( However, ozone will automatically generate if ionization chamber is not sealed)

3. Stronger magnet ( This is too basic. could use electromagnet, but than we'll lose some energy to do that )

Expected Results: What?

Able to create efficient ion thruster with high output density.

Cost: How much will it cost

• Brain power

• Materials

• electricity

Problem Statement:

Current ion thruster is too weak to use in atmosphere.

Present State- Desire State:

Survey should done in multiple way , aiming to research document for ion thruster.

Source-Cause:

Creating efficient and stronger ion thruster will definitely be a core steps for better future.

KT(timing,trend,impact):

Due to limited weight that space industry and organization could shoot up to space, ion thruster is almost only choice they could use for spacecraft's thruster. As traditional combustion turbine is suffering lack of efficiency , depends on its altitude, ion thruster is having much higher potential than combustion turbine that already close to its limit.

Possible Problems:

There are limit to material, budget, and structural problems.

Design each task in a problem -solving effort so that its the most fruitful and provides most information or guidance. Define design goals and solution path.

1. Much dense ionized propellant. ( Plasma can be fasten by magnetic field. Maybe a tokamak could help. ) ( Not just dense plasma, but need to transfer gas to plasma faster. )

2. stronger electric field. ( Was thinking using tesla coil, but only high frequency won't effectively work to ionize xenon or hydrogen. )

3. Stronger magnet ( This is too basic. could use electromagnet, but than we'll lose some energy to do that )

4. Higher exhaust velocity ( maybe we can use Lorentz's force)

Maybe this is too unrealistic but we do know a phenomena that shows much faster plasma ejection in space. Solar wind. Will it be possible to mimic this?

Search and include relevant results of the design proposal for any of the following: trademark or service mark, copyright or copyleft, patent.

MIT aerospace engineering team was able to create small model aerocraft that use ion thrusting able to fly about 60m around 10 s. This model plane use EAD system which is a system create ionized wind. However, this plane wasn't able to take off by itself.

Problem Model

Essential task to solve is to create system that either eject more propellant or eject propellant with higer velocity.

Desired Functions or Goals

• Higher plasma density

• enhanced electric and magnetic field.

• stronger output

Partial Concepts or Means to achieve Goal

• Denser plasma

• stronger propulsion.

Identify potential hazards in the design

• Using gas that are not noble, could cause explosion.

• Ozone that will create by stronger electric field could not just damage the system, but also dangerous for human ( but this could be prevented)

• cost

Provide solutions to the elements hazards of proposed design

• seal ionization chamber so minimum or none of oxygen could get in.

• use noble gas. ( xenon)

• Hope I could find sponsor.
