Competition rules of turbofan and turbojet model aircraft

In 2006, Harbin Engineering designed its own sailing model competition rules: 1. The model specifies 1. The Electrical and Electronic Experiment Teaching Center provides students with 1 set of ship model power drive (380 DC motor), 2 sets of power batteries (voltage 7.2V) and 1 set of four-channel proportional remote control equipment. 2. The structure and shape of the ship model are designed by the students themselves, in order to make use of the waste materials at hand, such as beverage bottles, packaging boxes and so on. 3. It is required that the materials used in the ship model shall not pollute the pool. The operation of the motor should be controlled by radio. 5. The model should have a fixed bracket and a number plate installed vertically on the deck. The number plate must be made of opaque white material with black numbers on both sides. 6. Self-designed models should have high cost performance and novel ideas. 2. Competition rules: 1. The ship model competition is divided into two rounds. The first round is a single boat crossing the buoy in the water. The total time of this round of competition is 5 minutes. In the 5-minute race, you can set sail many times, you can touch the model by hand, but you can't replace the battery. Before each voyage, the assistant should raise his hand to signal the referee to record the time and record it at the best time. 2. Each race voyage model must sail twice in the triangle area. (clockwise and counterclockwise) is a complete flight. 3. The width of the competition buoys is 1m, which is triangular. Players can get 20 points for each set of buoys. When the model touches the buoy, it will be deducted 10; If the model does not enter the buoy, it does not score. 4. In the second round of competition, 3-8 models should participate in this round of competition at the same time, and the total time of this round of competition is 5 minutes. Sail counterclockwise in the triangle field and count one lap after all buoys. Within five minutes, the inner circle won many games, and the top four in the preliminary round entered the next round of finals. 5. The flight position of the contestants is decided by the lottery of each group. 6. Before sailing, check the radio remote control devices to prevent mutual interference. At this time, all remote control devices should be turned on, and no objection is allowed after it is confirmed that there is no interference. 7. Models can touch the bid, but they can't miss it. If there is a missing bid, it is allowed to bypass the bidding again without disturbing other participating models. If there is no rebinding, the circle is invalid. 3. Performance evaluation: Only self-made models are allowed to participate in the competition, and the performance consists of two parts: the first part is the competition performance, accounting for 80%. Specificity: 1. The first round-evaluate the performance of the players by the time (seconds) to complete the specified route. The sum of the scores obtained is the best result of this round. 2. The second round-evaluated by the total number of laps completed by the competitors within 5 minutes of the specified route. The sum of the results of the two rounds determines the final result. The second part of the vehicle design, mainly examines the cost performance and innovation of the vehicle, accounting for 20%. Specificity: 1. The referee has the right to make a ruling on acts not stipulated in these rules. 2. Encourage teams to decorate and beautify their models, so as to make them innovative. The sum of the two results of the contestants determines the results of this competition and ranks them.
