Our last post reviewed many possible features or forms to use in line staging for space launch.  Not all are destined to see use, but many have been considered by others before us.  By re-posting these early ideas we make them available to the engineers, who may be assigned to develop the best features into flying hardware,

Investors should be aware of the potential to add safety features, and the cost in mass penalty of each.  In line staging proposes to eliminate a little drag, enhance lift a bit, and reduce the vehicle mass slightly.  Wings return an option in case of power loss or explosions.  These gains will be cancelled by too many luxury ideas added on later.  I have seen advertising art create concepts that engineers cannot get off the runway.

There are investors looking at this and other solutions to space access.  I know that readers on this blog are doing the kind of research that investors might be doing.  A few readers are doing a large number of views of many pages on this site.  That indicates a change towards more research and detailed study.  Previously viewers were making few tours of the whole site, just hitting the main page.

Two popular pages seem to be “Nuts” and “Mars Voyager”.  They suggest the difficulty of the journey ahead.  Another WordPress blogger offered this history of the French Hermes project:

I pointed out in my “Nuts” post that this all depends on teamwork.  The Hermes was influenced by the international effort on the space station and other nation’s problems.  Our efforts are under the influence much of the same confusion.  So many ideas and technologies divide the plans for space exploration.

Who can solve the problems and focus efforts on effective solutions?  Investors had to be smart to become prosperous, but they are challenging a new field of expertise.  Hired experts are divided on the best answers.  Each launch technology may have a unique niche in the market.  But fixed and rotary wing aircraft serve unique needs in the atmosphere.  I expect that vertical and horizontal launch will also find their niche in service.  The investor has to recognize the paths that will mature to real service.  We need to get the scientists and engineers to identify our best features for them.

This winged launch is best suited to manned operations where wings offer comfort and safety advantages.  Heavy lifters may be better served with vertical launch.  This horizontal concept needs professional evaluation and refinement.  Investors will require confirmation from their own experts before they will sign on to a radical concept.  We will have some market use in earth flight, but orbital space flight really is a giant leap.  So we have to move to design professionals to satisfy the investors.

Mission: Analyze and optimize aerodynamic options and orbital mechanics.    These must be accomplished with the maximum safety consideration for manned flight operations.  There are challenges that few have analyzed for horizontal launch orbital mechanics.  We have introduced new aerodynamic ideas to analyze.  Development will not be a short simple procedure.  Manned operations will be the most demanding possible development and operation.

Study assignment: Wayne Hale’s blog.  This relates the conditions that undermined safety on the most sophisticated orbiter in history.  We need to be armed with this kind of humility and suggested diligence.  I hope our competition will not demonstrate the urgency of this mission before the market is mature enough for our entry.
