What is the problem of moon dust?

• The researchers observed that after the Moon mission, the eyes of the Apollo crew were watered and their noses flowed. In longer-term missions, cancer cases may be encountered, and even death may result.
• Dust particles are charged with charged particles from space, thereby adhering to surfaces; Spacecraft and astronauts create great problems.
• Moon powder particles; It kills 90% of the cells by chemical reaction with lung cells. In experiments conducted on mice, it is observed that the powder also destroys neurons and nerve cells.

HOW WE PLAN TO SOLVE THIS PROBLEM?

Despite the problem of moon dust; Due to the low fuel consumption and the static effect of lunar dust, Hall Effect, an electromagnetic static propulsion system that neutralizes the released atoms, designs an unmanned space vehicle by periodically taking the solid sample from the lunar surface with the optical trapezoidal screw system and analyzing the dust generated by optical dust sensors. to map the moon dust. Unmanned Aerial Vehicle Covered Transparent; solar panel and peltier system design meets the energy need, the vehicle provides sustainable operation with wireless charging.

The hall effect, one of the electrostatic magnetic propulsion systems, covers a distance of 3% of the fuel used by the rocket engine. While the rocket engine consumes 280 tons of fuel in 3 minutes, it reaches a speed of 2,000 km / h and electromagnetic static propulsion systems can work continuously for years with low fuel consumption and reach high speeds of 40,000 km/h.

The advantage of using the hall propulsion System in the moon dust task is that the electrons emitted from the cathode at the final outlet neutralize the charge of the expelled xenon atom, which provides an advantage over static sticking of the intermediate moon dust.

The acceleration of electromagnetic static propulsion systems is disadvantageous compared to rocket motors. If the trunk disrupts its parallel position to the ground, the impulses will be perpendicular to the ground, thus losing stability in the direction of the slope. The transmission of power to the propellers such as a drone in the atmosphere in the world cannot be controlled by the method of balancing. Here we encounter an engineering mechanics problem. For this reason, the propulsion systems must always be positioned perpendicular to the ground. We have provided 8 servo motors in our model prototype by connecting these motors in a vertical way and moving them in x and y axes according to the data we received from the 6 axis gyro sensor. Even if the trunk lost its parallel position to the ground, we were able to position the thrusts perpendicular to the ground and recorded it in detail. At the same time with our mobile application tool; We have successfully commanded forward, backward, right, left movement.

Taking the topographic map with LIDAR sensor on the lunar surface, taking solid samples from certain rock groups depending on the periods of orbital change and temperature changes in the moon, analyzing the amount of dust formed during sampling by using optical dust sensors, forming the pollination scale and forming the pollination scale. Current and sustainable mapping of existing and possible pollination status.

Since solid sample is taken from the moon surface, it cannot be taken by vacuum method in an atmosphere independent from the atmosphere ‘Lunar Source Book - See Chapter 7- page 509’’ According to the information we received, we designed the solid sampling and optical folding drill with trapezoidal screw.

Although it provides the opportunity to make a choice depending on the dust map we have extracted, the space shuttle will land in the lunar missions, despite the necessity of landing to the desired area in different situations, it can be prepared by using the polyurea A-338 pu, landing pad as a 3d printer. moon dust and static effects.

We collected antistatic lanterns to obtain energy, collect solid samples, and wirelessly transfer the obtained energy to the vehicle and optimize the solar energy coming to the solar panels.

By generating energy from solar panels and examining NASA data, seeing the difference in temperature between day and night by about 250 degrees Celsius and turning it into an opportunity to generate electrical energy from the temperature difference with the highest and lowest material specific to a surface of the developing peltier system. We have planned. We planned to store this generated electrical energy in a battery and transfer it wirelessly to the vehicle. By leaving the solid rock sample collected in the trapezoidal screw to this station, we have made it possible to fill the xenon fuel from this optical drill station from the station so that the vehicle can be used independently for months as an external support for many years.

We planned to autonomously cover the top surface of the vehicle with a solar panel in the event that it was ineffective by determining the route around this station based on the remaining fuel and energy status.

TeamWork and WorkSharing

Team leader M.K.HARLIOGLU created the idea of the project and provided the model prototype parts until the competition day and took care to start production on the competition day. By analyzing prototype design according to the advantages and disadvantages of electronic system design and propulsion systems used, it produced realistic and innovative solutions despite its disadvantages. One of these was the problem of orientation caused by acceleration of the hall affect in the electromagnetic static propulsion system used.

With the 6-axis gyro module, it took the inclination data and controlled the propulsion systems in 2 axes and 4 directions by connecting the two servos perpendicular to each other and made basic guiding movements through the bluetooth module and mobile application. Since vacuuming cannot be performed due to lack of atmosphere in solid sample collection on the surface of the moon, Nasa designed the trapezoidal screw drill system using moon lunar dust book data and prepared the optical landing design of this drill. Prepared the landing gear, depending on the distance sensor, gave the model realism. He designed the energy generation system and realized the wireless charging system by investigating the materials with maximum and minimum heat value specific to the upper and lower surface of the developing peltier system in the charging station.

Software engineer B.KILIC did research to find the solution to the problem of stepper motor control, and managed to control stepper motors at a critical time. He undertook the necessary internet research for those in need of help in the team and succeeded in the organization within the team. He searched the presentation visuals and found documents related to the researched topics. He contributed to the timely training of tasks by solving systemic problems. Accelerated data transfer by moving presentation files between computers. He made the decision of the necessary program in the use of design simulation engine and analyzed the techniques to be used and made suggestions to the team. Unity also supported the team by conducting the necessary research on the design problems encountered.

Simulation officer S.GEYIK decided to participate in the competition and took online unity design courses until the day of the competition to obtain information that could produce products. He tried to design similar to the prototype of the model that emerged on the day of the competition, and made an ideal simulation to obtain cinematic images to describe the necessary axiom designs. However, he had difficulties in detail movements. He tried his best to correct the visually unacceptable factors in the designs. He completed the task by uploading the used codes to github.
