SpaceX – Breaking the $1000 per Pound Launch Cost Barrier
John Strickland explains how SpaceX can drive launch costs to less than one
tenth that of competing rocket systems:
“When people see this cost comparison, they ask all over again ‘How
can he (Musk) do that?’ How can the Falcon outperform the Delta by such a
wide margin? The three main reasons seem to be (1) low manufacturing cost (2
) low operational cost (time efficient operations design and low man-hours
needed per launch) and (3) high efficiency performance in flight. The first
two have already been demonstrated by the Falcon 9, and they continue to be
improved, such as a recently announced two-thirds reduction of fuel loading
time. The SpaceX paradigm is one of continuous improvement.
The first reason (low manufacturing cost) is exercised again in the “
Heavy” by using three nearly identical rocket stages (instead of two solids
and a core stage), which means more production of the same units, thus
reducing their unit cost. The SpaceX plant in Hawthorne, California, is
building towards the capability of producing a Falcon 9 first stage or
Falcon Heavy side booster every week and an upper stage every two weeks.
Within five years, SpaceX expects to be producing more large rocket engines
per year (several hundred) than all other rocket companies on the planet
combined. Engine production costs will thus decline still more. (Dragon
production, depending on demand, is planned for a rate of one every six to
eight weeks.)
The third reason (high efficiency in flight) is partly achieved by the
standard methods of making the engines fuel efficient, with high thrust and
low mass, and making the overall structural mass of each stage as low as
possible. Musk has apparently done this better than anyone else. For example
, the two side boosters have a fully fueled to empty mass ratio of 30.
Additional flight efficiency is achieved by propellant cross-feeding (see
below).”
Elon Musk talks more about the SpaceX cost advantage here. SpaceX is
breaking from industry norms by being up front about their launch prices and
publishing them on the web. Click here and scroll down to see the price for
a Falcon Heavy launch ($83 million) and that the payload it will be able to
carry to LEO is 117,000 pounds. That works out to $709 per pound, less than
the $1000 per pound BTE goal for the Heavy Lifter to be used for launching
the Enterprise components into space. And the ‘Falcon Super Heavy’ which
is not yet shown on the SpaceX site should have an even lower launch price
per pound. SpaceX is certainly blazing a whole new trail. |

因为两边的是booster,助推器,比中间的一个更早脱离,中间一个的顶上有第二级。
如果三个绑三角,就必须同时和第二级脱离,那么就多花了燃料在不必要的重量上了。
而且这样就和和Falcon 9显得太不一样,不适宜于采用同样的结构和设计。

真正有意义的平均价格是你能频繁发射的平均价格,在能够满足载荷的轨道要求的前提
