The technical term for this week is: Pressure

Termo: Pressão

É um termo da física que se refere sobre uma certa força aplicada sobre uma determinada área, no caso do planador ela é responsável por manter o aeromodelo em constante movimento aerodinâmico de planeio, resistindo a queda e alcançando uma certa distância.

Term: Pressure

 It is a term of physics that refers to a certain force applied on a certain area, in the case of the glider it is responsible for keeping the model airplane in constant aerodynamic movement of plane, resisting the fall and reaching a certain distance.

11º semana

Essa semana foi finalmente realizada a prova de planeio da equipe que obteve um resultado insatisfatório devido a diversos fatores, sendo o principal o corte de custos para construção do protótipo, levando ao aeromodelo ser feito com materiais mais baratos e com menor eficiência, na prova de planeio, realizada no dia 15 de junho de 2019, o aeromodelo conseguiu alcançar as distancias de aproximadamente: 18 m, 13,9 m e 8,9 m. A prova consistia em 10 lançamentos do topo do prédio do CIMATEC 4 (11 metros de altura), os 3 melhores lançamentos receberiam um média e de acordo com os valores definiríamos a razão de planeio, infelizmente a equipe não alcançou os seus objetivos e obteve um planeio <1:3. Apesar dos resultados baixos, o planador se mostrou muito resistente sendo necessário apenas pequenos reparos durante cada lançamento. A seguir alguns vídeos dos melhores lançamentos da equipe:

This week was finally accomplished the result team's glide test due to factors, the main one being the cost cut for the construction of the prototype, leading to the model airplane being made with cheaper materials and with less efficiency, in the airplane test, carried out on June 15, 2019, the model was able to reach distances of approximately: 18 m, 13.9 m and 8.9 m. The test consisted of 10 launches of the CIMATEC 4 building (11 meters high), the first 3 entries received in an average and according to the values would configure a glide ratio, but a team did not reach its objectives and 1 < 3. Most movies are made up of a glider, a glider, or a napkin for each launch. Here are some videos of the team's best new releases:

The technical term for this week:Centre of gravity

Centre of gravity is when the total weight of the body may be thought to be concentrated, this is as if the object behave as if the whole body weight was concentrated on him. The concept is sometimes useful in predicting the behaviour of a moving body when it is acted on by gravity.
Many people confudem the center of gravity with the center of mass, because they think that they are the same thing and this is a mistake because the center of mass is the point where we can assume that all the mass of a body is concentrated and that all external forces acting at this point since the center of gravity represents the point where the weight of the body act.And to show the difference and I'll show you an example  the Moon’s centre of mass is very close to its geometric centre (it is not exact because the Moon is not a perfect uniform sphere), but its centre of gravity is slightly displaced toward Earth because of the stronger gravitational force on the Moon’s near side.

10ª semana

   Na décima semana o foco do grupo foi nas compras de novos matérias, nas construções dos componentes e na montagem do planador final para a avaliação do teste de voo. Para as compras dos matérias foi necessário discutir os principais erros do primeiro planador, sendo eles; a resistência a tração e torção do planador, seu peso, entre outros fatores que desfavoreceram o planeio do primeiro planador, com isso em mente o grupo decidiu trocar a madeira para pinus flexíveis por ser mais resistente e colocar um corpo de polímero rígido que foi o PVC. A dificuldade nas construções dos componentes no primeiro planador foi principalmente na hora do corte, logo o grupo se reuniu e decidiu fazer corte a lazer na madeira para facilitar o processo, como mostra a figura abaixo:

  Com o corte a lazer da madeira foi mais fácil a montagem o grupo se reuniu durante toda a semana para sua montagem, como mostra a figura abaixo:

   In the tenth week the group's focus was on purchases of new materials, the constructions of the components and in assembling the glider for final evaluation of the flight test. For purchases of materials was necessary to discuss the main mistakes of the first glider, being them; resistance to traction and torsion of the glider, its weight, among other factors that desfavoreceram the plan of the first glider, with this in mind the group decided to change the wood for pinus flexible to be more resistant and put a body of rigid polymer that was the PVC. The difficulty in the constructions of the components in the first glider was mainly at the time of cutting, soon the group met and decided to cut the leisure activities in the wood to facilitate the process, as shown in the figure below:

   With the cut the pleasure of Madeira was easier to assemble the group met throughout the week for your assembly, as shown in the figure below:

The technical term for this week: fuselage

                                                  fuselage

The fuselage is the protection layer that conects the wings and the empannage and, in the normal airplane, is the part that allocates the passengers. But in the glider we only use the fuselage only to conect, because of that we need to chose a fuselage that is good in the aerodynamics.

9ª semana

No dia 31/05 foi feito o primeiro teste de lançamento, com a asa do primeiro entregável. O teste foi feito do solo pelo fato de que o acesso até o ultimo andar do CIMATEC 4 estava bloqueado. Após o teste percebemos diversas mudanças a serem feitas no produção do nosso planador, até mudanças quanto aos materiais utilizados. Mesmo esse sendo somente um planador de teste ajudou na evolução do conhecimento da equipe quanto a construção do aeromodelo. Segue abaixo um vídeo de um dos lançamentos feitos pela equipe.

On 05/31 the the grup did  the first test launch, with a wing of the first deliverable. The test was in the ground because the access to the CIMATEC 4 was blocked. After the test, we realized a lot of changes to be made in our production of our glider, until material changes used. Even this being only a test glider, helped in the evolution of grup's knowledge regarding the construction of the model airplane. Below is a video of one of the releases made by the grup.

The technical term for this week: empennage

The empennage is a structure of the airplane consisting of the fuselage end part and the vertical stabilizers (steering rudder that guides the aircraft to the left or right), and horizontal (up or down movement controller). The joint composed by the fuselage of an aircraft comprises the wings and the empenagem. The empennage is the part located in the rear region being responsible for the longitudinal and directional stability of the airplane.

It is composed by the elevators, responsible for the pitching movements, which are to go up (to climb) and to prick (down) and the rudder responsible for the yaw movements that are swerved to the right and turned to the left.
