Robin: pravda ale k tomu pojizdeni s vypnutymi motory to neni daleko:)

trend: jsi(poznámka redakce:brzděte se ve výrazech)...to teda neví každý, APU slouží pouze jako generáto el. energie, kdyžř jsou vypnuté motory (baterie by to vse neutáhla) a dále slouží k tomu, že pouští je vzdch (tzv. APU BLEED) do klimatizace, nebo do motoru, aby se roztocili a ty je mohl nahodit, APU nepohání kola!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! letadlo taxuje díky jeho tryskovým motorům, né APU, kola letadlo netáhnou, pouze umožnují jeho pohyb po zemi. Vyděl jsi nekdy taxovat letadlo s vypnutými motory?? (samozřejmně neberu převoz do hangáru, kde jej táhne pushback car). Ještě mi řekni, že ilot když chce taxovat, tak schová knipl, vytáhne volant, řadící páku, bly, brzdu a spojku!!

To Petr Volek: A nepohani? Dyt to vi preci kazdy ze pohani. To je jasny

trend: Nechceš tu snad tvrdit že APU pohání kola? :-)

to Trend: myslím si, že "The engine includes a forward-facing main turbine shaft......The transmission assembly is releasably connected to the auxiliary equipment. In a first operating mode, the engine is operated at a low setting to power the auxiliary equipment. In a second operating mode, the turbofan engine is used to provide thrust and operate auxiliary equipment." znamená v podstatě to samé. Netvrdil jsem, že je to stejné APU jako na B737... Je to zjevně úplně jiná jednotka, pravděpodobně asi s fanem.

to Bob737 nemas pravdu!
APU provides speed and torque conversions from a rotating power source to another device using gear ratios. The most common use is in motor vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel.

pro Mechanika:
Auxiliary Power and Thrust Unit - United States Patent 6247668 - An improvement to an aircraft is provided in the form of an aircraft auxiliary power and thrust unit located in the tail cone of the aircraft. The unit includes a turbofan engine, an air intake opening, an inlet duct extending between the air intake opening and the turbofan engine, a transmission assembly, and various auxiliary equipment. The engine includes a forward-facing main turbine shaft. The air intake opening is located in the tail cone at a body station location forward of the engine. The transmission assembly includes a drive shaft mounted axially to the main turbine shaft and extends forward through the inlet duct through a sealed opening in the inlet duct. The auxiliary equipment is also located in the tail cone, forward of the turbofan engine. The transmission assembly is releasably connected to the auxiliary equipment. In a first operating mode, the engine is operated at a low setting to power the auxiliary equipment. In a second operating mode, the turbofan engine is used to provide thrust and operate auxiliary equipment.

Tomáš Bláha: v tom "stanu" také parkují letadla :-)

Kulatá střecha, ATR... To je hangár E? Nevíte někdo, co to naproti vyrostlo za podivnej stan?

By člověk blil z toho co se tady dočte za sračky.... Jedinej normální popis APU tu má Falcon!!!!
