| - | Based on this ethical and deontological analysis the team now understands which kind of challenges of that field they might face while developing the project. Having done the research the decision is to follow the Code of Ethics for Engineers by National Society of Professional Engineers while advancing in the project. While marketing the product the team strives towards an honest and transparent attitude and aim to be ethical towards the customers and also competitors. For the environmental point of view, the weight could be on power, which makes the vehicle move - the wind. The product has no emissions and the ecological footprint is small. Ensuring, that all of the components made, the suppliers worked with and the overall product itself would comply | + | Based on this ethical and deontological analysis the team now understands which kind of challenges of that field they might face while developing the project.

| - | The rigid sail has two main components: wing and tail. The purpose of using a tail is to control the direction of the main wing using a servomotor and because the tail is much smaller, there is lower consumption of power. This method is much more efficient if it's compared with no tail wing, that is using a servomotor that requires much more power to change the direction of the wing. | + | The rigid sail has two main components: wing and tail.

| - | The biggest stepping stone in the whole of the building process was the error in the first solution of the front steering. When the frame for the sail car was completed and put on wheels, it became obvious that the car is really difficult to steer with feet and it basically does not turn at all. The front wheel turned to either left or right steered the whole car in the same direction only a really minor amount. The reason behind the problem was discussed and found, that the fork of the front wheel was attached to the frame with a too little angle. Therefore, the wheel fell too much to the side while turning, and the forces coerced the wheel to fall even more to the side, rather than going back to the neutral position. As a solution, the team consulted with the supervisors and it was agreed, that it would be more reasonable to build the steering system in a way, that the front wheel would turn to either side, more like a normal car wheel, not tilt to left and right, like on a motorcycle.\\ | + | The biggest stepping stone in the whole of the building process was the error in the first solution of the front steering.

| Another setback occurred, when one of the longer ribs went missing from the laboratory in LSA, so the interns had to produce a spare part, which took some time so the whole building process of the wing was delayed. | Another setback occurred, when one of the longer ribs went missing from the laboratory in LSA, so the interns had to produce a spare part, which took some time so the whole building process of the wing was delayed. | ||
