Everything about Fuji Spacecraft totally explained
Fuji (
ふじ) is
capsule type manned
spacecraft concept,
proposed by Japan's
National Space Development Agency (NASDA) Advanced mission Research center when
December 2001. But, the Fuji concept wasn't adopted.
Background
As for
Japan, manned space flight depended on
USA Space Shuttle, and independent development wasn't taken up as short mid-term target. Moreover, the opinion that recommended
RLV with wing such as Space Shuttle and
HOPE was a majority, because Fuji proposal this time was before the
Space Shuttle Columbia disaster.
However, Fuji was proposed as one of candidates of flagship mission after reorganized into
JAXA from NASDA. Fuji chose a method of disposable capsule type, because considered that RLV had problems in cost and safety, and it was also possible to develop by using a mature technology in a short term of eight years.
Design
Fuji consists of two or more modules, and is combined by the usage.
Minimum System
Minimum System has ability of
Reentry capsule and
space flight of 24 hours. It was scheduled to develop at the early stage.
- Core Module (CM) » CM is base of Fuji. Crews of three, cone is diameter of 3.7m, gross weight of 3t or less. It has thrusters for position control and rocket engine of small thrust. Manufacturing cost aims at about 800 million yen each.
Standard System
Standard System adds two modules to a Minimum System. It has ability of space flight of 1 month and flight to the
moon orbit.
Expansion Module (EM) » EM is a living module. It is used by a long-term space flights.
Propulsion Module (PM) » PM has rocket engine for the orbit change and solar cell paddle.
Economy System
Economy System aims at lowering cost for space travel, based from Minimum System.
Low-cost version Core Module » Low-cost version CM is developing for space travel, based from Normal CM. Crews of five (Passengers of four).
Other module
An additional module was planned.
Space laboratory module » It has the heat radiation mechanism.
Robot arm module » It has the manipulator arm.
Simple living module » A module of inflatable type like a pumpkin. It uses by space travel.
Feature
Ensuring of safety by disposable » Fuji ensure enough safety by adopting a common technology by disposable capsule type such as escape rockets and ablator.
Accurate landing by entering by lift and Parafoil » Fuji does an accurate landing by an automatic control using GPS. Finally, it aims landing in the ground base by pinpoint.
Open architecture » Fuji adopts the open architecture method because of a decrease in cost, promotion of technological development, and an expand market. Details are shown as follows:
:It discloses information in the machine/electricity/thermal interface etc between system/subsystem. » :It doesn't restrict use of this interface in legally/money.
:It provides the test criterion of system/subsystem including safety. » In addition, Fuji's launch isn't limited to H-IIA.
Advanced Concepts
A variety of use ideas after CM had been achieved were planned.
