立法者要求NASA加速重型火箭(开发)
Lawmakers want NASA to speed up heavy-lift rocket
BY STEPHEN CLARK
SPACEFLIGHT NOW
Posted: June 23, 2010

A letter to President Obama from a bipartisan group of 62 members of the U.S. House of Representatives proposes a compromise plan to immediately develop a heavy-lift rocket, saying it would preserve jobs and America's leadership in human spaceflight.

The letter, dated June 22, calls for NASA to start developing a new heavy-lift propulsion system immediately, leveraging five years of work and $10 billion invested in the Constellation program before President Obama ordered its cancellation earlier this year.

"We support the immediate development and production of a heavy-lift launch vehicle that, in conjunction with the Orion Crew Exploration Vehicle, may be used for either lunar or deep-space exploration to an asteriod and beyond, as you said in Florida," the lawmakers wrote to President Obama.

During a visit to the Kennedy Space Center in April, the president unveiled plans to select a heavy-lift rocket design by 2015, leading to human expeditions to asteroids in the 2020s and eventually Mars as soon as the 2030s. President Obama also used the speech to announce the Orion capsule, originally designed to go to the moon, would be a lifeboat for the International Space Station.

Both announcements came after members of Congress criticized the Obama administration's NASA policy, which initially contained no timetable for human exploration beyond low Earth orbit and completely scrapped the Orion capsule.

Heavy-lift rockets are a critical piece for any space exploration architecture beyond Earth orbit.

"I urge the president to embrace these core principles to ensure continued U.S. leadership in space," said Rep. Frank Wolf, R-Va., the ranking member of the House Appropriations Committee's subcommittee overseeing NASA. "The immediate development of a heavy-lift rocket and crew capsule to take American astronauts beyond low Earth orbit is something that all supporters of NASA can unite behind."

Tuesday's letter, heralded as a compromise by its signers, indicates there is still considerable bipartisan concern over the White House's plans for NASA.

"We hope the administration is willing to work with us on the compromise," said Rep. Gene Green, a Democrat from Houston. "It is an important step in ensuring we save our valuable workforce and keeps America as the leader in space exploration."

Signed by 37 House Republicans and 25 Democrats representing 18 states, the letter says expediting the design and development of a heavy-lift rocket would save jobs, capitalize on lessons learned in the Constellation program, and ensure the country remains at the forefront of space exploration.

"This would provide operational flexibility while ensuring our taxpayers' investments have not been made in vain," the representatives wrote.

The lawmakers claim a heavy-lift rocket could be ready within six years with no increase to NASA's exploration topline budget.

"With no significant technological breakthroughs on the horizon in regard to heavy-lift propulsion needs, we see no reason to prolong a decision that will result in the loss of a highly-experienced and motivated workforce," the lawmakers wrote.

NASA is already seeking advice from industry on heavy-lift rocket concepts. The next-generation launcher would likely be powered by a massive kerosene-fueled rocket engine, but other options are still on the table.

Sen. Bill Nelson, D-Fla., wants to continue development and testing of the solid-fueled Ares rocket, which he says is key to keeping skilled defense workers employed. The Ares 1 and Ares 5 rockets, which would burn solid and hydrogen propellants, would be shelved under Obama's plan.

Tuesday's letter did not mention commercial crew transportation to low Earth orbit, another major policy shift under President Obama's budget request.

航天飞机 衍生重型 火箭,做国际空间站后勤和运输 评审大纲
http://www.nasaspaceflight.com/2010/06/sd-hlv-review-iss-transport-reliability-of-design/


SD HLV Review Outlines ISS Logistics and Transport
June 24th, 2010 by Chris Gebhardt  
As part of the comprehensive 700+ page study of a truly Shuttle Derived Heavy-Lift Vehicle (SD HLV), a preliminary assessment of an SD HLV’s capability to deliver cargo (and potentially crew) to International Space Station (ISS) has been performed, demonstrating the first part of an SD HLV’s multi-use potential should this vehicle be chosen as America’s new Heavy Lift vehicle in 2015 (in accordance with President Obama’s current timeline for America’s future in space).

ISS Operations:

The first review to gain mention in the SD HLV presentation was the vehicle’s potential use for logistics transfer of 45 to 65 metric tons – depending on the configuration of the payload flown – to the ISS, a payload to ISS capability that far exceeds any existing vehicle for ISS resupply efforts.

To begin the logistics transfer operation, the SD HLV would be inserted into a preliminary orbit of 30 x 120 nm using the combined thrust of two 4-segment SRBs and three SSMEs (Space Shuttle Main Engines).

An ISS logistics carrier, with an RCS and propulsion module attached, would then conduct the necessary course adjustment burns to complete phasing, approach, and docking operations with the Station between two and four days after launch.

Given the large “payload/large volume capabilities” that the SD HLV would provide, the opportunity to manifest multiple ISS logistics payloads would be a crucial ability of the vehicle.

“Potential future HLV missions that make use of the unique large payload/large volume capabilities of HLV may include multiple manifests of ISS logistics, replacements for ISS components, and ISS extension missions (Crew Rescue Vehicle placement, expansion modules and transportation node facility elements),” notes the extensive SD HLV assessment presentation, available on L2.

In correlation with this assessment, the presentation notes some of the potential payloads that could be launched by the SD HLV, including numerous external components (such as Nitrogen Tank Assemblies, Ammonia Tank Assemblies, and control movement gyros), up to two MPLMs at one time, the European Space Agency’s (ESA’s) Automated Transfer Vehicle (ATV), Solar Alpha Rotary Joint components, solar arrays, as well as replacement radiators.

This logistics version of the SD HLV would use the existing SRB (Solid Rocket Booster) design, a propulsion module/payload carrier to deliver its payload to a preliminary Low Earth Orbit using three SSMEs throttled nominally at 104.5 percent, and a Logistics Carrier complete with propulsion module for orbit circularization, phasing, and rendezvous with the ISS.

However, in addition to purely logistics missions, the SD HLV could also be used to ferry crews AND cargo to and from the ISS.

During ascent, the CEV (Crew Exploration Vehicle) would ride on the top of the logistics carrier inside of the combined propulsion/payload module. A Launch Abort System tower would be fitted over the CEV to provide a critical ejection system that would yank the CEV away from the SD HLV stack in the event of a launch mishap.

The first stage of flight would utilize the existing twin SRB design combined with three SSMEs on the propulsion module of the SD HLV.

Following SRB staging, the payload fairings and Launch Abort System would be jettisoned at T+250 seconds (T+4mins 10secs) at an altitude of 351 kft at Mach 8.08.

Following MECO, the logistics carrier (with Orion CEV, ISS payload, and a small propulsive module) would separate from the payload carrier/propulsion module (which will still be attached to the External Tank). Then, the small stage propulsion module on the logistics carrier would fire to circularize the orbit to 120nm.

Then, the Orion CEV would be released from the “top” of the logistics carrier and reposition itself by docking to the aft end of the logistics carrier.

After proper phasing maneuvers, the Orion CEV would perform a series of propulsion maneuvers to rendezvous and dock the logistics carrier to one of the Pressurized Mating Adaptors (PMAs) on the ISS two to four days after launch.

Orion would then undock from the aft of the logistics carrier and dock to a separate PMA on the ISS.

As always, MOD would be responsible for launch through end of mission operations.

Concerns identified during the assessment phase include the command and control ability of the Orion/CEV on an SD HLV, hardware and software modifications for an Orion flight on SD HLV, and post-MECO control of the SD HLV stack by Orion from MECO through logistics carrier separation from the HLV.

For the Orion SD HLV option, the Orion CEV would be the long pole item, with five other concerns currently listed in the “red.”

Furthermore, the assessment identified preliminary ISS cargo concerns, including the fact that ATV, HTV (Japanese Transfer Vehicle), and Russian Progress all support current ISS resupply requirements, and the potential modification of the Orion service module element to allow for payload resupply of ISS.

Furthermore, carrying the ATV as cargo would require hardware and software changes to the ATV as well as a potential new service module “to assist with control authority.”

Also, Orion and ATV sensor locations for proximity ops with the ISS would be blocked by the logistics carrier.

WASHINGTON — A bipartisan group of more than 60 members of the U.S. House of Representatives wrote to President Barack Obama Tuesday urging that he direct NASA to immediately begin development of a heavy-lift launch vehicle capable of sending NASA’s Orion Crew Exploration Vehicle on deep space missions.

In a June 22 letter to the president signed by 62 House lawmakers, including 25 Democrats and 16 members of the powerful House Appropriations Committee, the members say it is in the nation’s best interest to leverage the $10 billion NASA has already invested in Constellation,  a 5-year-old effort to replace the retiring space shuttle with Orion and the Ares family of rockets. Obama marked the program for cancellation in his 2011 spending proposal delivered to lawmakers in February.

“We support the immediate development and production of a heavy-lift launch vehicle that, in conjunction with the Orion Crew Exploration Vehicle, may be used for either lunar or deep-space exploration to an asteroid and beyond, as you said in Florida,” the lawmakers say in the letter. During an April 15 speech at NASA’s Kennedy Space Center, Fla., Obama said NASA would continue development of Constellation’s Orion crew capsule for use as a lifeboat aboard the international space station and would spend up to five years studying heavy-lift propulsion technologies before initiating development of a heavy-lift launch vehicle no later than 2015.

The lawmakers assert that a “heavy-lift exploration system could  be operational within six years and achieved within NASA’s Exploration topline budget.”

NASA’s Exploration Systems Mission Directorate stands to receive a total of $23.6 billion between 2011 and 2015 under White House budget projections released in February. That figure includes $3.1 billion for heavy-lift and in-space propulsion research, $6 billion to foster development of commercial crew systems and $12 billion for various advanced technology research and demonstration projects.

“With no significant breakthroughs on the horizon in regard to heavy-lift propulsion needs, we see no reason to prolong a decision that will result in the loss of a highly-experienced and motivated workforce,” the lawmakers state in the letter, which was spearheaded by Rep. Gene Green (D-Texas) and three members of the House Appropriations commerce, justice, science subcommittee that oversees NASA spending, including the ranking minority member Frank Wolf (R-Va.) and Reps. C.A. “Dutch” Ruppersberger (D-Md.) and John Culberson (R-Texas).

While the lawmakers say a robust U.S. deep-space exploration program would ensure that NASA astronauts explore beyond low-Earth orbit to the Moon, Mars or “any number of exciting destinations,” they remained silent on the president’s plans to privatize operations in low Earth orbit, an omission that did not go unnoticed by at least one company seeking to develop a crew transportation system for missions to the space station.

“It looks like Congress is on the right track, encouraging the Administration to move forward as quickly as possible with heavy-lift,” said Lawrence Williams, vice president of strategic relations at Space Exploration Technologies (SpaceX) Corp.  “Since President Bush unveiled his Vision for Space Exploration in 2004, the plan has been that NASA would focus its development efforts on moving beyond [low Earth orbit] and use commercially-developed rockets to service the [international space station].”

Hawthorne, Calif.-based SpaceX  has spent roughly $350 million in NASA funds since 2006 to develop the Falcon 9 rocket and Dragon capsule with astronaut transport in mind.

也不知他们要折腾个啥?其实4个加段srb+6台肉丝68b就挺好的。

再重新走航天飞机衍生受制约太大,毕竟那一套是40年前的设计,怎么改也得从头到尾重做一遍,还不如抛开它重起炉灶,航天飞机的经验和数据仅拿来参考就是了。

要么就把大煤油或天然气啃下来把srb踢了也是一种办法。至于德4那样的全氢氧,成本不好说啊。

俺还是很喜欢类似战神一+战神V这样的配置的,单根打25吨标准件,凑一起打2百吨特大型物资。这不挺好嘛。

美参议院通过折衷的NASA法案 加紧研制重型火箭和乘员舱

新闻发布时间:2010-07-16

  [据美国航天新闻网2010年7月15日报道] 美国参议院商业委员会7月15日通过两党立法,延缓白宫使用私营企业火箭运送宇航员的计划,同时加速研制重型火箭和乘员舱,以支持深空载人任务。
  
  法案将批准NASA直到2013年的经费规模,并将航天飞机计划延长一年(即该舰队定于2011年退役),且支持国际空间站任务至少到2020年。奥巴马政府官员称,法案支持了奥巴马2月份提交国会的NASA 190亿美元开支计划的主要方面的内容,包括5年增加最高60亿美元投入,延续空间站任务至2020年,以及终止星座计划(在该计划下,NASA正研制“战神”火箭和“猎户座”乘员舱,以替代航天飞机运送宇航员到月球)。
  
  根据参议员纳尔逊公布的法案摘要,法案将阻止NASA在2012年以前采购任何商业宇航员出租载具服务,并且要求开展研究以保证对任务的“有效监管”。依靠商业乘员出租载具服务运送宇航员出入空间站是白宫计划的重要方面。纳尔逊称,法案提出的重型火箭时间表比奥巴马的计划更具挑战性,2011年启动,基于航天飞机和星座计划的技术,达到能将至少130吨重的货物送入轨道的能力。奥巴马于4月指示NASA要在2015年前确定重型火箭的设计。
  
  “对于重型火箭,该法案比星座计划更强调加快发展(原定2018年才启动)。”政府官员在声明中称,“总统已提议比星座计划更早研制重型火箭,这将进一步加快进程,我们就可以在2020年代初开始载人飞行。”
  
    法案还提出:基于“猎户座”技术的深空探测乘员舱,要在2016年末准备投入运营。(中国航天工程咨询中心 王宜晓 陈菲)

感觉SD-HLV(航天飞机衍生型) 无论怎么衍生,也不会达到130吧?现在的航天飞机最多才25吨,乘以多少才130吨啊?130吨都赶上初级N1了。

现在的航天飞机是只算货仓载货量的,不计轨道器本身重量,这么来的25吨。

构型改变后,去掉了沉重的轨道器本身,把轨道器上的SSME搬到燃料箱上,实际上就变成了美国版的“能源”。这样的重型火箭,载荷就有一百多吨了。

只是简单估计噢,也没有仔细看过SD-HLV的英文介绍,只是觉得啊,轨道器没了,只是少了3个翅膀和载人舱,整流罩之类的东西还应该在吧,3个翅膀和载人舱加起来也没有100吨重吧---所以就有了以上的想法。
