First homework

 This is our first homework of this course. With this activity, we have a first view of the parts of the plane which makes it flies and be airworthy. 

Airplane parts and function


 1. Describe the following aircraft motions.
1. Pitch: up and down movement of the plane’s nose/on the horizontal
axis.
2. Roll: The rotation movement of the wing tips of the aircraft
3. Yaw: The side to side movement of the nose. Swaying motion side to
side of the nose of the plane / moving from left to right using the rudder.
4. Loop: A complete roll
5. Dive: Decrease the inclination of the nose / downward motion when
the plane lands.
6. Climb: to go up (movement of plane)
7. Lift: A force which pushes the plane up.
2. What are the functions of the parts of the airplane pictured above?
1. A: Vertical stabilizer: controls the yaw movement, keep the nose of
the plane from swinging from side to side.
2. B: Rudder: directs the tail left or right / changes yaw movement.
3. C: Elevator: changes pitch
4. D: Horizontal stabilizer: controls the pitch movement. (the up and
down movement of the nose)
5. E: Flaps: increase lift and drag
6. F: Aileron: Roll the wing from side to side / change roll
7. G: wings: flat surface which generate lift.
8. H: Turbine engine: generates thrust
9. I: Fuselage: holds everything together
10. J: slats: increase the lift.
4. Which parts are used to control lift at low speed for takeoff and landing?
Slats, Flaps and soilers
5. Which parts, installed one to each wing, operate in opposite directions (i.e., one up and one down)?
The ailerons operate in opposite directions.


6. If the part in Problem 4 on the right wing is up and the one on the left wing is down, what will the airplane do?
The plane will roll right
7. If the pilot lowers the elevator, what will the airplane's tail do?
The tail goes up and the plane will dive.
8. What will this in turn cause the airplane's nose to do?
The nose of the plane will dive
9. If the pilot moves the rudder to the left, what will the airplane's tail do?
The airplane’s tail will turn to the right
10. What will this in turn cause the airplane's nose to do?
The airplane’s nose will turn to the left
11. What motion will occur in an airplane with the elevator deflected up and the rudder deflected to the right?
The airplane will climb and turn to the right.
12. What is a spoiler?
A spoiler is a plate that are used to disrupt the flow over the wing and change the amount of force by decreasing the lift when the spoiler is deployed.

Racing drones

A Drone is a flying device controlled remotely by a person or a program to develop many types of functions. There are many types of drones but my favorites are the racing drones. These devices are controlled by people who use a control with two joysticks and glasses where you can see in real time what is in front of the drone. Be careful if you are a person with vertigo or fear of speed. The device is normally built by four high performance electric motors that provide support and addressability to the device; a battery that gives electrical energy; a camera that allows you to control the drone as if you were inside and some circuits that control the motors and send the video signal to the glasses. There are a variety of forms of these devices: with more engines, with steerable propellers or even amphibious water-air. They are devices that don't allow a great time of flight, but can reach speeds of up to 130 kilometers per hour. Their flight range doesn't reach a kilometer aw...

Sushi and bad weather

This week, my in-laws they planned to come a few days to visit Mallorca and be with my girlfriend and me. Due to weather forecasts, they changed the day of arrival and advanced the trip a few days. From what they said on the news, it was going to rain a lot this week and the wind was going to blow very hard. These days we went to eat at two restaurants. The burguer Doze, is a small restaurant in Llucmajor that makes a very good burgers at a good price; or to kiyomi sushi, which is a Japanese food restaurant that has a menu where you can choose everything you want with a fixed price. The sushi is of very good quality and the entrees are very good. My in-laws left to Menorca a day before the storm began. This storm was announced well in advance, as it could cause a lot of damage to coastal areas and flood areas. Finally there have been waves up to 14 meters high and winds of up to 120 kilometers per hour. It has been days of staying at home in the afternoon. In the practice hours in Glob...

Maintenance Technician Course

In this post I will talk about how to obtain the title of superior technician in aeromechanical maintenance and how to obtain the license of technician in maintenance of airplanes B1.1 which is the necessary license to be able to sign in the documents of a commercial turbine aircraft. I will explain how to access these studies and what are the advantages of studying at the IES Son Pacs. I have selected some questions that may come to your mind before starting the course and that can help guide you. -How can I access these studies? As it can be accessed in several ways, in each course there are limited places for people who access through the bachillerato degree, other places for people who access by an vocational course of the same family or another family, there are also places for who access with an entrance exam to the university or an entrance exam to a vocational course. -Where do classes take place? During the first course, classes are held every Monday at the IES Son Pac...
