About The Competition:

With the advanccements and developments in technology of Unmanned Aerial Vehicles (UAVs), they are developing their fields of activity and used it vastly day by day. UAVs have the capability to access remote or dangerous areas, facilitate environmental monitoring and capture high-resolution imagery. These flying objects are helpful in monitoring as they bridge the constraints in limited-access, dynamic, harsh and complex environments and defence applications. This competition is focused on the application area that requires to provide UAVs with the capability to perform specialized strategic missions including Surveillance and dropping the payloads in the designated areas. UAVs have already largely taken over the reconnaissance activities worldwide from using the level of human intelligence in terms of high environmental awareness, decision making ability and planning ability in dynamic environments.

RULES & REGULATION: 

• In this category the school students of maximum 4 members can team up together and can participate in this competition. 
• Each Team’s glider will be subject to technical inspection by the jury members. 
• After inspection the team will be allowed to launch their glider and best flying model with time of flight will get the award as per the scoring issued by jury members. 
• Participants are to ensure that the glider is built strong, but to also keep it light; while adding some nose weight to maintain a good CG for balanced and stable flight. 
• The glider is to be placed on the runway of the official launcher with its fuselage hooked onto the bungee cord.
• The glider is pulled back to the point which exerts 2kg of thrust on the model. Any further and that attempt is considered void.
• Participants must be mindful of how they release their glider on the catapult, as any last moment pulls will be considered as a foul launch and also render that attempt void. 
• The distance recorded will be based on the glider’s first contact with the ground after being launched. The remaining distance which it slides is not taken into account.
• Each participant is allowed 2 attempts. Each participant may have a spare glider and ready in the event that one fail or broken. The spare model need not be of the same design. The contestant shall have the spare glider ready for 2nd attempt when called upon.  
• The better of the 2 flights will be considered as the final result for scoring. The glider that clocks the longest distance from the launcher will be the winner. 
• There will be no sharing of models during the event. Participants who borrow a model in order to compete will be disqualified immediately. Participants who allow their model(s) to be used by others during the competition will also be disqualified. 
  I. Hence, all gliders must have the name and school of the participant written clearly on the wing of the glider. 
• Models will be kept with Jury members till the end of the competition. 
• Decision of the jury members are final.

UAV Technical Specifications and Restrictions:  

In general, UAVs will be subjected to technical inspection by the competition committee in terms of safety before the competition. According to the result of the examination, the team's participation in the competition will be approved. Teams that fail the technical inspection cannot participate in the flight. The technical inspection area will remain open throughout the competition. Teams that have a breakdown or fail to pass the technical inspection can enter the technical inspection at any time during the competition period with the approval of the jury. Teams whose technical inspection is not completed until the start of the competition cannot participate in the competition. UAVs must have safety systems (failsafe mode) in case of communication interruptions (see Safety Requirements for details). UAVs can be autonomous or controlled (manually) by remote control. In the design and production of UAVs, teams can use off-the-shelf products, including the platform (fuselage, wing, engine, etc.) and subsystems. The propulsion systems of UAVs should consist of battery-powered electric motors. There should be a fuse on the UAVs that switches the motor power line. This fuse can be blade type or button type. Fuses made using a 'jumper' cable connector on the motor power line will not be accepted. 

Physical Limitations of UAVs: 

The UAVs must not weigh more than 5kg. UAVs will be weighed together with the maximum take-off weight during the technical control, UAVs above the limit will not be able to pass the technical control. There is no limitation in terms of size and number of motors. 

UAV Battery Limitations: 

The vehicles that will participate in the UAV competition must use well-known and proven battery technologies as the main power source. In addition, the batteries used must be safely positioned inside the vehicle. Batteries must be brightly colored to make them easy to spot in case of an accident. Vehicles whose energy source is deemed dangerous by the jury will definitely not be allowed to fly. In case of any accident, the competitors are obliged to safely remove their batteries from the competition area and not leave them in the competition. 

LANDING: 

A successful landing is defined as a controlled return to the ground inside the landing zone for that class and remaining on the ground through rollout. A failed landing attempt will result in no score for the round.
