THE BIG LIFTER

HANS THE HEAVY LIFTER

My monster plane seemed like pie in the sky at first, but the higher I aim the more down to earth it seems to get.  Proposing to displace the Space Launch System with a reusable design is a bit bold.  This is appropriate to be known as the White Rose in memory of another outspoken movement during the Second World War.  Resistance to error may require a bold statement.  With the previous radical thoughts on runway operation considered, the first stage launcher aircraft is a prime interest.

Aerodynaimc knowledge is growing and exploring new solutions for future designs.  Past experience with flying wings and Bernoulli’s lifting fuselage suggest new efficiency potential.  Blended wing bodies offer lower drag, stronger structures, lower weight, and greater internal volume.  These seem ideal for near space applications like our booster.

Initial studies indicate that the wing body has ample volume for the first stage fuel load proposed for the Space Launch System.  The result is not a monster airplane, but a fairly reasonable sized cargo plane.  This is comparable to proposed blended wing designs, and smaller than some operational cargo planes today.

A BLENDED WING BODY TANKER

A booster stage is essentially a tanker so this is not an unreasonable comparison.  As these fighters are matching the speed of the tanker, our upper stage is also essentially operating as another aircraft in parallel flight.  The difference is that our booster is providing the propulsion for the upper stage.  But the orbiter is contributing the needed wing area without parasitic drag or increased frontal area.

 AND FOR “HANS”, OUR FIRST STAGE BOOSTER AIRCRAFT:

 

                     HANS  
Crew 0
Length: 183
Wingspan 269
Height 30
