Fred Talasco's May entry is a unique two stage
model designed to be flown with a cluster of 3 18mm motors in the booster. This
design also supports a single engine booster.
The email from F Talasco has this to say:
Here is my design of the month entry for May.
The rocket is a two stage, clustered, 13mm 'Space Plane' design that I have been working
on for some time. In this design, I sought to combine several advanced techniques, with a
pleasing, futuristic design. The booster stage can be flown with a single motor or a
cluster of three. One of the rather unique features of this design is the booster stage
recovery system: The upper 'scramjet pods' house twin streamers that are attached via
kevlar to the booster. When the sustainer ignites, the booster drops away, pulling out the
streamers. Due to the large fin area, the sustainer stage comes down almost sideways,
protecting the large fins from damage.
I have named the rocket ELT for Earth-Luna-Transport. The boilerplate rocket has been
flown a number of times, in sustainer only single stage, single engine booster stage, and
clustered booster stage configurations. The rocket has been a success on every flight, in
every configuration. I intend to paint this rocket gloss white, with early Orbital
Transport type decals for that classic look.
I have enclosed a design sheet with parts list, photos of the model, and some thrilling
launch photos. Unfortunately, this type of design cannot be simmed using Roc-sim.
In 2035, American Spacelines introduced the ELT
(Earth to Luna Transport) to replaced the aging fleet of Orbital Transports. Due to
advances in rocket motor design, the smaller more efficient reusable three motor first
stage allowed the new design to avoid the large launch 'carrier' of the previous craft.
This designs passenger/payload section was a greater percentage of the rocket's
total mass, and was able to carry almost twice as many passengers and/or cargo as the
previous two piece design. This more efficient design meant lower costs, and allowed
for the first true space tourists.
Features include two stage 13mm power, with an
optional triple clustered first stage. Recovery for booster is dual streamers, while
the second stage has a 12" parachute.
