APOLLO SPOT LANDING & APOLLO EGGLOFT SET ALTITUDE
APOLLO SPOT LANDING RULES
OSL RULES INCORPORATION
- All of the rules contained in Rule 60, SPOT LANDING, of the US Model Rocket Sporting Code are hereby incorporated into this contest.
- Specifically, this is an Open Spot Landing contest where any type of rocket, low-power motor (up to G impulse), and recovery method (except radio control – Rule 60.3) is allowed.
- Scoring shall be determined in accordance with the procedure in Rule 60.8, with the exception noted in the Contest Procedure below.
ADDITIONAL APOLLO LANDING SITE RULES
- Instead of one target spot, there will be 6 targets, each representing a successful moon landing site (Apollo 11, 12, 14, 15, 16 and 17).
- Each of those sites will offer a single premium prize, which will be awarded at the end of the competition per the rules below.
- The six Apollo landing site target markers will be placed on the landing area of the sport range in a regular hexagon. The size of the hexagon will be determined on the first day of the event.
- Each competitor is allowed only one official flight attempt. No practice flights are allowed (Rule 60.7).
- When an official flight attempt is completed, the scorer records the distance IN METERS TO THE NEAREST CENTIMETER from the tip of the nose cone to the TWO CLOSEST target markers and records the measurement to each target on the flight card. If it is equidistant to two targets, the scorer will record the same distance in both places.
- The determination of winners for this contest is as follows:
- Each flight card’s two measurements will be recorded on a spreadsheet.
- The spreadsheet will be sorted by distance for each target landing site, in numerical order (Apollo 11 first, ending with Apollo 17). The flight landing closest to that site wins.
- Once a landing target’s winner has been determined, that contestant is removed from the pool of entries (only one prize per contestant will be awarded).
- The spreadsheet will be sorted again by distance for the next landing site, and the process above will be repeated until all 6 landing site winners are determined.
- In the event of a tie for any particular landing site, the winner will be determined by random draw.
- The judge’s decisions shall be final.
APOLLO EGGLOFT SET ALTITUDE
- The target altitude is 1969 feet above ground level (AGL) for this event. All contestants shall attempt to achieve this same Set Altitude.
- Rockets used for this event will carry a payload of three USDA Large hens eggs. Eggs may be arranged in any arrangement, e.g. side by side or in tandem.
- Damage to any of the eggs shall disqualify the flight.
- Only a single official flight is permitted in this competition. Official flights shall be declared prior to model launch by completing a competition flight card. There is no limit on flights of the entered model at a rocketry event prior to declaring an official flight.
- The entry may not separate into two or more unattached components in this event. Flights shall be recovered by a minimum of one parachute.
- Models will utilize only a single rocket motor; the total impulse shall be no less than 160.01 Newton-seconds and no greater than 640.00 Newton-seconds.
- The entry shall not utilize any means of external control to control the altitude of the model (e.g. remote control).
- Altimeters for the first deployment event must be set to apogee detect.
- The Contest Director will provide all eggs (USDA Large hen’s) for this event. Eggs will be numbered and/or uniquely marked to indicate their source. Egg identification will be recorded on the flight card at the time of issue. Eggs will not be screened for weight or diameter for this event.
- All entries shall be returned following their flight for altimeter reading and egg inspection. Egg enclosures shall not be opened until presented to a contest official for post flight inspection.
- In the event of multiple altimeters, the RSO will average the reports and round to the next-highest 1-foot increment to get the reported altitude.
- The altitude error will be calculated as the absolute value of the difference between the reported altitude and set altitude.
- The percentage error will be calculated as the altitude error divided by the set altitude and the result multiplied by 100.
- The entry with the lowest percentage error and a qualified flight is the winner.
