1 ROCKET CONTEST CONTEST TERMS AND CONDITIONS

2 Terms and Definitions: Payload: Any system circling an orbit or falling in trajectory from a specific altitude designed to complete a scientific/commercial/military task during/after the fall. A closed experiment mechanism released to fall down from an altitude of 120 km designed to observe the effects of micro-gravity in space is also defined as a Payload system. Rocket: Any transport vehicle of various sizes, running on various types of fuel and capable of carrying out a variety of tasks depending on the Payload being transported, designed to deliver Payload at a specific altitude. Rocket design limitations and criteria are specified in the document. An exemplary rocket placement layout is also available in Appendix 1. Recommendations: Any statement made by the contest committee which may be useful for a safe flight but is not necessarily considered a rule to be followed. All recommendations are available in Appendix 2. Category: Contest location options determined by the contest committee subject to specific limitations. Contest is held in 2 different categories. The reason for this is to give the contestants the opportunity design rockets with differing thrust and size specifications. Final Report: Final detailed report submitted to the contest which must include the exact specifications of the competing rocket. Ignition Wire: Wire which can ignite fuel and/or combustible material when an electrical current is passed through its open ends. Ground Station: Device which controls the ignition process of the rocket (to be supplied by the contest committee). In addition, this is used for communicating with and controlling the rocket during flight (each team must bring their own stations). Engine: Thrust unit found in thrust systems. There are 3 different types of fuel systems namely liquid, solid and hybrid fuels. Class: Rocket engines fall into different international classes depending on their thrust levels. Commercial engines competing in this contest may not be bigger than M Class. Flight Computer: Main controller unit which controls the flight of the rocket and stores various readings with the sensors. Eyebolt: The intermediary component in the shape of an eye which is used for connecting the parachute with the remaining systems of the rocket. The following example illustrates this system.

3 Example of an eyebolt Commercial System: The term commercial system refers to two subsystems. These are the flight computer and thrust systems.. In this document, commercial thrust systems are referred to as Commercial Rocket Engines. This type of rocket engines are ready-to-use engines having design and production operations being carried out by the vendor. These engines are considered not to have any originality. Commercial flight computers are also sold in this manner and they are also considered not to have any originality. Integration Body: Integration body of a rocket is used to connect the two continuous bodies of a rocket which has the same outer diameter as the inner diameter of the rocket. Ramp: Launching station from which the thrust system takes off. Launching station is set at a specific angle in accordance with the terms of the contest. Static Margin: Static margin is the ratio of the distance between the centre of pressure and the centre of gravity of the rocket to its diameter. Stable State: State where the static margin of the rocket is between 1.5 and 3. Reusable Rocket: A rocket is considered reusable if it can be used for consecutive flights after post-flight recovery and control operations are carried out and only by simply replacing its fuel. Reusability of a rocket depends on the damage inflicted on its body, flight computer and engine parts before, during and after the flight and their reusability status. The rocket may be prepared for another flight once the necessary damage evaluation, repair work and inspection is done. This requires a high level of inspection. Reusable Payload: Payload which may be prepared for another flight after landing attached to the rocket or independently, once the required inspections are completed. Reusability may depend on the damage inflicted on the Payload body and scientific components. The rocket may be prepared for another flight once the required damage inspections and repair work is done. Rail Button: This is the lead attached to the body of the rocket using mechanical parts which is used for mounting the thrust systems to be launched on the launching ramp in a linear manner. A minimum of two Rail Buttons are mounted on the rocket body. The integration of Rail Buttons with the rocket is the responsibility of the teams. The linearity of Rail Buttons is checked by the contest judges.

4 Risk Analysis: The analysis work which should be conducted by the competing teams according to the specified criteria for their respective rocket designs. A sample document of the analysis will be shared after the summons for the contest. Check List: Each team is required to have a list ready on the location of the contest area which is used to check that all the material and the entire assembly process is complete regarding their rockets. A sample check list will be shared after the summons for the contest. Staged Rocket: Staged rockets have multiple thrust systems which separate from the main system in stages during flight. Staged rocket systems are divided into parallel and serial staged systems. Open Rocket: An open source code software used for simulating the flight of rockets in altitude rocketry. Link: 1.

16 Appendix-1: Open Rocket Sample Document

17 Appendix 2: Recommendations Primary Parachute Deployment: Primary parachute should deploy at peak altitude. The rocket should not roll in the air. Falling speed of the rocket should be slowed down. However, in order to prevent the rocket from drifting to much in the wind, falling speed should be slowed down to 20 to 40 m/sec by deploying the primary parachute. Secondary Parachute Deployment: Secondary parachute should be deployed no earlier than 600 m and no later than 400m from the ground. It should be descended at a maximum rate of 9 m/sec and a minimum rate of 5 m/sec to prevent damage to the vehicle and its parts. Launching Stability: Vehicles should reach sufficient Track Speed During Launch to ensure that they will follow a predictable course. A rate higher than 30 m/sec guarantees that the rocket will follow a predictable course. Alternatively, teams must prove theoretically (computer simulation) or empirically (flight tests) that the rockets can maintain stability at a lower Track Speed During Launch. Track Speed During Launch will have been proven in the Open Rocket file attached to the final report submitted before the contest. Static margin is the distance between a rocket s pressure and gravity centers in terms of diameter. If the static margin of a rocket is larger than its diameter, the rocket is considered stable. If the vehicle s static margin is larger than both body tube diameters, it is considered over-stable. Overstable vehicles should be avoided. Safety: It is recommended for teams who want to carry out trial launches and thrust tests with their own means in order to base their efforts on code 1125 of the US National Fire Prevention.
