Марс Аэростат

[Палкин]

В "НК" было много сообщений про испытания аэростата который полетит к красной планете (сначала М - 94 потом М - 96 а потом закрыли). Но фоток не было. И детально устройство не описывалось. Кто что знает напишите :!:

Там про аэростат ничего дельного. Я спрашивал про фотки и детальную конструкцию :!:

Какие фотки? Написано же - дальше эскизного проекта не пошло. Есть только такие картинки:



И вот такие абстракты:

Several concepts for a Mars aerobot (robotic balloon) mission have been pursued in the last decade: Russian-French Mars Aerostat Project (1987-1995)[1], Mars Aerial Platform Discovery Proposal (1994)[2], Mars 2001 Aerobot/Balloon Study (1996)[3]. The Mars Aerostat was a full-scale mission (~600 kg entry mass) with a payload of 15 kg and 15 kg of the "snake" guiderope. The aerostat floated at an altitude of ~ 4km during the day, when it was slightly overpressured, and descended to the surface during the night when the envelope cooled using a guiderope to prevent the envelope contacting the surface. The expected lifetime was < 7 days.

The Mars 96 balloon mission involves: an orbiting spacecraft, a descent module, and a balloon to which are attached a gondola with scientific experiments and a stabilizing element named guiderope. An overview of the guiderope mission and characteristics is given. The guiderope's primary mission is to stabilize the Mars balloon during the night, after its descent, in order to avoid the balloon and the gondola contacting the ground. The guiderope has a snake like shape to avoid snagging when dragged on the Martian surface. Its length is 7 m plus a 7 m cable tail. Its mass of 13.5 kg allows the guiderope to house various scientific payloads, management system and its initialization device, a transmitter, its antenna and the batteries. The duration of the mission is ten days after 10 months of transfer from Earth to Mars.

The guiderope is intended to enable the balloon to fly close to the Martian surface to sample the surface and near-surface atmosphere. The 'Snake' concept is described for this application which comprises overlapping cones that provide a smooth dragging surface as well as structural flexibility. A 'tail' segment of small diameter is attached to the Snake that stabilizes the guiderope with titanium shells and also serves as half of the required radar dipole antenna. A specific design is set forth for the Snake and Tail elements that provides dust-tolerant effectiveness without lubricant for the extreme conditions of the Martian surface.

На Марсе на аэростате особо не полетать... Об гору шмякнется быстро))

The Mars-94 balloon mission [...] Potential landing sites were selected taking into account the scientific objectives, orbitography limitations, and balloon criteria. Northern latitudes are more suitable for relief and terrain characteristics. In the selected areas, the ground altitude is in the 3 to 1 km range (6.1 mbar zero reference). Three regions were investigated in more detail: Utopia Planitia, Arcadia Planitia, and Acidalia Planitia. [Blamont, 2008]

Как я понимаю, вверху (оранж) - тормозной парашют, в центре (зеленый) - надувной баллон на 5500 кубов высотой 45 метров и диаметром 12 метров, внизу - научная аппаратура зонда, по бокам - шарики с гелием для наддува баллона.
