Korean Rocket Unha 3
Contest Directions: North Korea's keenly watched rocket launch has failed, Pyongyang has confirmed. North Korea says the aim of the launch was to put a satellite into orbit - a move marking the 100th anniversary of the birth of national founder Kim Il-sung. But the US and other nations say the launch constituted a disguised test of long-range missile technology banned under UN resolutions. The failure of this launch is embarrassing for the North Korean regime. It had been billed as a sign of the North's technical achievement. The 100ft (30m) rocket named "Unha-3" exploded into some 20 pieces and fell into the sea, after flying for just over a minute.
Since the design of "Unha-3" is a top secret, we can only guess what caused the rocket failure - from bad engineering design to clumsy assembling, to bad fuel or poor choice of materials. Today you are going be a Korean rocket scientist, and suggest the alternative designs of "Unha-3" that may be rejected by North Korea for any reasons (e.g. think of some alternative materials or obvious engineering flaws).

        • Kim needs to be casting a shadow on the roof of the building (or, based on the soldiers, on the ground) and the rocket and see-saw need shadows as well.

          Not trying to criticize, but it looks weird right now without them, and the voters are going to go off on you if you don't fix this (if you care about that).
        • See Saw blast off !!!! really a clever job done

        • They may resort to this method at the rate they are going.
        • This is really perfect concept, keep your Rocket at 45 degree and target...Booom
        • This concept was used by me when i am 6 years old now i am seeing it again very funny

This contest is fueled by the following news: Rocket engines: Most current rockets are equipped with chemical rocket engines, which can use solid propellant, liquid propellant, or a hybrid mixture of both solid and liquid. The chemical reaction between propellant and oxidizers start in the combustion chamber, and the resultant hot gases accelerate out of a rocket engine nozzle (or nozzles) at the rearward-facing end of the rocket. The acceleration of these gases through the engine exerts force ("thrust") on the combustion chamber and nozzle, propelling the vehicle (according to Newton's Third Law) Application: Military, Rocket weapons (missiles): Rockets are used to propel the decimators to their targets. The small size and high velocity of the rockets help to ensure their low vulnerability. Thus no pilot is required to control a combat missile, which can carry charges of great destructive power, including nuclear charges. Modern systems of homing and navigation ensure high accuracy and maneuverability of the rockets. There are many different types of missiles, which differ by the range of flight, as well as by the start point and the place of target defeat ("earth" - "air"). Anti ballistic missile systems are used to combat missiles. There are also signal and illumination flares. Science and research: Airplanes and balloons launched to study the Earth's atmosphere can reach altitudes of 30-40 kilometers. Rockets do not have such restrictions and are used to probe the upper atmospheric layers, mainly mesosphere and ionosphere. Rockets can be divided into light meteorological rockets, capable of lifting a set of instruments to an altitude of about 100 kilometers and heavy geophysical rockets, which can carry several sets of instruments and whose flight altitude is practically unlimited. Usually research rockets are equipped with instruments for measuring atmospheric pressure, magnetic field, cosmic radiation and composition of air. They also have equipment for transmitting the results of the research to the earth via radio. Some models of rockets allow the data obtained during their flight descend to the ground with the help of parachutes. Rocket meteorological studies preceded satellite studies, therefore the first meteo satellites had the same set of instruments as meteorological rockets. The first rocket for studying conditions of the air environment was launched on April 11, 1937; however, regular launches began only in 1950s, when series of specialized research rockets were created. Space exploration: Hermann Oberth is considered to be one of the founding fathers of astronautics, who was the first one to prove the physical ability of a human body to endure the overload which happens during the launch of the rocket and in the state of weightlessness. Due to the high exhaust velocity of the ignition products (M10+) rockets are particularly useful when very high speeds are required, for example for launching a spacecraft into the orbit of the Earth (see the first orbital velocity). The maximum speed, that can be achieved with the help of a rocket is calculated with Tsiolkovsky's formula, which describes the increase in velocity as a product of outflow velocity to the natural logarithm of the ratio of initial and final weight of the unit. A rocket so far is the only carrier capable of launching a spacecraft into the space. Alternative ways of getting a spacecraft into the orbit, such as a "space elevator", electromagnetic and usual guns, are still being designed. The key feature of a rocket the lack of necessity for the environment or external forces to ensure its movement - manifests itself most vividly in space. This feature, however, demands that all the components, required to create the reactive force were on the board of the rocket. Thus, for the rockets using such solid components as liquid oxygen and kerosene as fuel the ratio of the weight of the fuel to the weight of the structure reaches 20/1. Rockets working on hydrogen and oxygen, this ratio is much smaller - around 10/1. The weight characteristics of a rocket depend a great degree on the type of rocket engine and the expected limits of structural safety. The speed required for getting spacecraft into orbit is often unachievable even with the help of a rocket. The weight of the fuel, structure, engine and control system is so high that it does not allow the rocket to reach the required speed within an acceptable period of time. The problem is solved by using compound multi-stage rockets, which can eject the excess weight during the flight. Due to the reduction of the total weight of the structure and burnout of the fuel acceleration of the compound rocket increases in the course of time. It may descend slightly when the exhaust stages are ejected and the engines of the next stages start. Such multi-stage rocket, designed to launch spacecraft, are called launch vehicles. Rockets used for the needs of space exploration are called launch vehicles (carrier rockets) as they carry a payload into space. Most commonly used launch vehicles are multi-stage ballistic missiles. The carrier is launched from Earth or in case of a long flight from the orbit of an artificial Earth satellite. At present, space agencies of different countries are using the launch vehicles Atlas V, Ariane 5, Proton, Delta-4, Soyuz-2 and many others.
