About
Demonstrator 2B
The technical solutions that we are using in the construction of the
STABILO and ORIZONT vehicles were previously verified on the demonstrators
rockets. The most successful was Demonstrator 2B. During the almost
two and a half years ARCA designed, constructed and tested on ground
and in flight three rockets and their sub-systems in order to be able
to build the ORIZONT and STABILO vehicles in the optimum configuration.

Demonstrator
2B is a modified version of Demonstrator 2, equipped with the world`s
first reusable rocket engine made of composite materials. The main objective
of this rocket was to test in flight the engine and the vehicle-launch
pad interaction in order to gather more data for the Orizont vehicle
construction. For the Demonstrator 2B launch was used the Demonstrator
2 launch pad which was modified (the length was increased to 18.2 m)
and also the command panel and fuel transfer facility previously developed
at ARCA. This rocket was the end of subscale systems tests at ARCA and
the beginning of the Orizont vehicle construction.
Characteristics
Length: 4.54 m;
Diameter: 0. 77 m;
Weigth: not yet disclosed
Thrust: not yet disclosed
Status
The program was completed on September 2004 during the X Prize Competition.
This rocket was used for the development of STRACAAT military aplication
project. The program was reactivated in 2009 for the Google Lunar X
Prize Competition.

About
Demonstrator 2
ARCA started the work to this rocket in May 2003. The entire structure
is made of composite materials. For this vehicle was created a whole
launch complex, including the launch pad, the fuel transfer facility,
etc. For this vehicle we proposed two propulsion configurations: monopropellant
and hybrid. Demonstrator 2 was the starting point for the development
of the successful Demonstrator 2B rocket. The first public display of
this vehicle took place in Dragasani, on September 27, 2003.

Characteristics
Height: 4.5 m
Diameter: 0.5 m
Wing span: 1.4 m
Total weight: 295 kg
Rocket
propulsion
The demonstrator can be equipped with 2 propulsion systems:
Monopropellant (thrust: 480 daN): hydrogen peroxide 70% as single propellant
Hybrid: hydrogen peroxide 70% as an oxidizer, in combination with polyethylene
as fuel
Capabilities
Monopropellant system: Predicted altitude: 8 600 m / Predicted speed:
302 m/s
Hybrid system: Predicted altitude: 20 000 m / Predicted speed: 465 m/s
Status
Even though the Stabilo and Orizont vehicles are ARCA`s main objective,
the development of the Demonstrator 2 rocket will continue, in order
to create a commercially available rocket for scientific applications
and for the Google Lunar X Prize Competition.
