Antonov An-72 - soviet producer 1/200

Die Antonow An-72 (NATO-Codename: Coaler) ist ein sowjetisches-STOL-Transportflugzeug für Kurz- und Mittelstrecken. Sie ist speziell für den Einsatz in arktischen Regionen konzipiert worden. Hierfür sind ihre beiden Turbofan-Triebwerke vor und über den Tragflächen angeordnet und führen den Luftstrom über die Tragflächen, um so den Auftrieb zu erhöhen (Coandă-Effekt). Außerdem wird so weniger Schnee eingesogen.

Die Maschine ist als Schulterdecker ausgelegt. Sie verfügt über ein einziehbares Bugradfahrwerk. Das Hauptfahrwerk befindet sich in Ausbuchtungen am Rumpf und ist damit kurz und robust. Es ermöglicht so den Einsatz auch von unbefestigten Pisten und Eisflächen aus.

Die Maschine hat ein hochgelegtes T-Leitwerk, sodass im hinteren Rumpfbereich eine Laderampe montiert werden konnte. Die hochgelegten Triebwerke helfen, die Start- und Landestrecken auf unter 500 m zu verkürzen (STOL: Short Take Off and Landing). Diese Anordnung wurde auch bei der Antonow An-32 verwendet, die aber über hochgesetzte Turboprop-Triebwerke verfügt. Der Erstflug fand am 31. August 1977 statt. Der erste Einsatz von insgesamt acht Vorserienmustern (davon zwei Antonow An-74) begann jedoch erst im Dezember 1985. Die Produktion wurde im Werk Nr. 135 in Charkow durchgeführt. Die sowjetische Luftwaffe übernahm die ersten Maschinen 1987. Seit Produktionsbeginn sind 102 Einheiten gefertigt worden, welche sich im weltweiten Einsatz befinden.

Lunar Landing Module "Eagle" - Revell 1/48 built by Bianca Krop-Kaiser

The Apollo Lunar Module (LM), also known as the Lunar Excursion Module (LEM), was the lander portion of the Apollo spacecraft built for the US Apollo program by Grumman to carry a crew of two from lunar orbit to the surface and back. Six such craft successfully landed on the Moon between 1969 and 1972.
The LM, consisting of an ascent stage and descent stage, was ferried to lunar orbit by its companion Command/Service Module (CSM), a separate spacecraft of approximately twice its mass, which also took the astronauts home to Earth. After completing its mission, the LM was discarded. It was capable of operation only in outer space, structurally and aerodynamically incapable of flight through the Earth's atmosphere.


Its development was plagued with problems which delayed its first unmanned flight by about ten months, and its first manned flight by about three months. Despite this, the LM eventually became the most reliable component of the Apollo/Saturn system, the only one never to suffer any failure that significantly impacted a mission, and in at least one instance (Apollo 13's LM-7 Aquarius) greatly exceeded its design requirements by maintaining life support for astronauts after an explosion damaged the Apollo Service Module.

Apollo Command Module - Revell 1/100 built by Bianca Krop-Kaiser

The Command/Service Module (CSM) was one of two spacecraft, along with the Lunar Module, used for the United States Apollo program which landed astronauts on the Moon. It was built for NASA by North American Aviation. It was launched by itself into suborbital and low Earth orbit test missions with the Saturn IB launch vehicle, and three times by itself and nine times with the Lunar Module as part of the Apollo spacecraft assembly on the larger Saturn V launch vehicle, which was capable of sending it to the Moon.
After the Apollo lunar program, the CSM saw manned service as a crew shuttle for the Skylab program, and the Apollo-Soyuz Test Project in which an American crew rendezvoused and docked with a Soviet Soyuz spacecraft in Earth orbit.


The CSM consisted of two segments: the Command Module, a cabin which housed a crew of three and equipment needed for re-entry and splashdown; and a Service Module that provided propulsion, electrical power and storage for various consumables required during a mission. The Service Module was cast off and allowed to burn up in the atmosphere before the Command Module re-entered and brought the crew home.
The CSM was initially designed to return all three astronauts from the lunar surface on a direct-descent mission which would not use a separate Lunar Module, and thus had no provisions for docking with another spacecraft. This, plus other required design changes led to the decision to design two versions of the CSM: Block I was to be used for unmanned missions and a single manned Earth orbit flight (Apollo 1), while the more advanced Block II was designed for use with the Lunar Module. But the Apollo 1 flight was cancelled by a cabin fire which killed the crew and destroyed the Command Module during a launch rehearsal test. Corrections of the problems which caused the fire were applied to the Block II spacecraft, which was used for all manned missions.
