Model rocket sport
With model rockets sport is called sporting competitions with model rockets . The model rocket sport is not very widespread in Western Europe, but very popular in Eastern European countries such as Poland, the Czech Republic, Slovakia and Bulgaria.
Types of competition
In the course of the model rocket sport, various competitions are flown. The most common are:
- Altitude competitions
- This is about the highest altitude reached. This is measured electronically with barometric altimeters . These mainly offer organizational simplifications, but they increase the weight of the rocket and are influenced by the weather. Traditionally, the height was measured with theodolites . To do this, the rockets together with the brake band eject a colored powder at the peak. The resulting cloud can be targeted more easily, but the measured height depends on whether it is possible to carry out the ejection precisely at the peak.
- Most of the regulations now stipulate minimum rocket sizes for high-altitude competitions. In this way, the flight altitude is limited by increased air resistance . In the past, it has often turned out to be problematic to deploy missiles such. Some of them are not much larger than a pencil and can be followed visually at altitudes of up to one kilometer .
- Endurance competitions
- The goal of endurance flight competitions is to keep the missile in the air for as long as possible, or sometimes a predetermined amount of time. Above all, the altitude, the size of the parachute and the weight of the rocket are optimized. Variants are also flown in which the rocket is recovered with a striker or by means of a rotary wing via autorotation .
- Scale competitions
- Scale models are true-to-scale models of real existing models that are mostly used in space travel or the military. Above all, the attention to detail is assessed, which must be proven with appropriate documentation. The prototypical flight is also included in the evaluation.
- Rocket glider
- The aim of the rocket glider, which behaves like a glider after takeoff with a rocket motor, is either the longest possible flight time or the most precise (temporal and spatial) landing at one point. The latter is done with remote-controlled gliders.
Regulations
There are various regulations that z. B. be set up by associations, clubs and organizers. The best known worldwide are the rules of the American National Association of Rocketry (NAR), the US Model Rocket Sporting Code (also known as the "Pink Book"), and that of the Fédération Aéronautique Internationale (FAI), the FAI Sporting Code .
NAR Sporting Code
The "Pink Book" of the American NAR has 25 classes, including altitude and endurance competitions, scale and payload classes. The beginnings go back to 1959. The Pink Book was also the model for the FAI's model rocket Sporting Code.
FAI Sporting Code
The FAI Sporting Code currently provides for the following classes:
- S1: Competitions related to the altitude
- S2: Load model competition (flying high)
- S3: Competitions regarding the longest flight time of the model including landing on the parachute
- S4: Competitions related to the flight time of rocket gliders
- S5: high-altitude flight competition with prototypical models (scale)
- S6: Competitions regarding the longest flight time of the model including landing on the Strömer
- S7: prototypical rocket flight models (scale)
- S8: radio-controlled rocket glider
- S8E / P: radio-controlled rocket glider with target and time landing
- S9: Rotary-wing endurance flight competitions
- S10: Flex-wing endurance flight competitions
- S11 / P: Model rocket aircraft and spacecraft
- S12 / P: three-way flight duration competition
Most of the classes are further subdivided into individual subclasses. For example, class S1B is an elevation model whose motorization may have a maximum impulse of 5 Ns, i.e. impulse class "B" .
IMR Model Missile Sports Code
The German-language "Green Book" of the interest group model rockets (IMR) includes seven model rockets sports competition classes: drag racing (drag race) , long-duration flight, designs, payload (Payload) , altitude record, salvage and Super Rocs. The rules are deliberately kept simple and the focus is on having fun flying. The competition classes are also intended to supplement existing model rocket competition regulations.
