26 November 2013 - The Executor 2 Rocket Engine fit-check on the test facility

ARCA performed a fit-check of the Executor 2 rocket engine, for the Haas 2B rocket, on the test facility. ARCA took the decision to develop the Executor 2 rocket engine as a fast and cost effective solution for the Haas 2B suborbital rocket. The Executor 2 rocket engine is fueled with LOX and kerosene T1 and it has a sea level thrust of 50,660 lb (23,000 kgf). It has a length of 7.2 ft (2.2 m) and a diameter of 3.23 ft (0.98 m). The engine's total weight is 550 lb (250 kg).





November 4, 2013 - The Executor rocket engine test facility is under construction

The Executor engine test facility is under construction. The Executor rocket engine is used by ARCA for the Haas rocket series and IAR-111 Excelsior rocket-plane. ARCA team cast 140 tons of reinforced concrete. Liquid fuel rocket engines of up to 80 tons of thrust could be tested on this facility. In the next weeks, the facility will be equipped with rocket engine feed lines and tanks and a water cooling system. The rocket engines command, control and working parameters measurement will be also added.





September 26, 2013 - First ARCA flight in the ExoMars Program completed successfully

ARCA has successfully completed the avionics qualification test flight for the ExoMars High Altitude Drop Test (HADT).
The objectives were flight testing the avionics and communication systems, demonstrating the containers sealing after sea landing and the capability to identify and recover the equipment from the sea surface.
The launch took place on September 16, 2013, from the Black Sea coast and comprised three pressurized containers containing the avionics equipment that will be necessary to test the ExoMars spacecraft parachute during the incoming future flights. The pressurized containers, carried by the cluster balloon, were launched at 7:15 AM and the ascension took 90 minutes to an altitude of 24,470 km. At this altitude the containers were released under a dedicated recovery parachute and landed on the sea, twenty minutes later. The containers and the recovery parachute were recovered by the Navy, at a distance of 92 km from the launch point.





September 2, 2013 - ARCA at DC-X 20th anniversary

ARCA was invited by NASA DC-X team to the 20th anniversary of the Delta Clipper Experimental first flight. ARCA presented the programs under development as the Haas 2C, 2B, IAR-111 and ExoMars.





May 19, 2013 - ARCA is developing a new Flight Command and Control Center

ARCA is developing a new Flight Command and Control Center. The new center has three new telemetry stations (radio and satellite) and two new command stations, passive radar, alongside two meteorological stations, CCTV system and other capabilities.





April 15, 2013 - ARCA completes the first phase of ExoMars High Altitude Drop Test Program

The European Space Agency has visited ARCA for two days in order to check the progress of ARCA regarding the preparations for the ExoMars High Altitude Drop Test Program. ARCA successfully completed the first phase of the program, the Design Review, and is now near to complete the first Drop Test Vehicle (DTV) for the first flight test, alongside the ground support equipment. This flight test, that will take place over the Black Sea, with the support of the Navy, will be a rehearsal for the two main flights that will take place in the autumn of 2013.





April 3, 2013 - Start of the Google Lunar X Prize 2013 Summit in Santiago, Chile

ARCA participated at the Google Lunar X Prize Summit held in Chile. The teams presented their technical and media efforts in the Google Lunar X Prize Competition. The competition regulation was also discussed.





December 28, 2012 - ARCA will test the parachutes for the ExoMars spacecraft

ARCA and the European Space Agency (ESA) signed a $1.1 mil. contract for the ExoMars, High Altitude Drop Test - Balloon Flight Services Program (HADT-BFS). During the contract, ARCA will contribute to the 2016 ExoMars spacecraft program by testing its parachutes, that will allow it to safely land on Mars. The cooperation decision was taken after preliminary meetings between ARCA and ESA. On these meetings, the European Space Agency presented the program's requirements while ARCA responded to these requirements by its own technical capabilities and expertise. ARCA will build two large high altitude balloons and two testing vehicles weighting more than half a tone each. The vehicle, named the DTV, or Drop Test Vehicle, will be launched from 30 km altitude, over the Black Sea. The vehicle will fall until it will reach a speed up to 0.8 Mach. At this transonic speed, the DTV will deploy the parachutes to test them in flight, in the simulated Martian atmospheric conditions. The flight data will be transmitted from the DTV to the ARCA's Flight Command and Control Center. Download press release here.





November 28, 2012 - The second stage rocket engine for the Haas 2C rocket

ARCA has completed the design for the second stage of the Haas 2C rocket. The second stage will be built from composite materials ( the kerosene tank) and 304 stainless steel (the oxygen tank). The tanks are pressurized at 16 atm from a 200 atm helium tank. The second stage is powered by the 5,500 lb (2,500 kgf) Venator rocket engine.





August 16, 2012 - ARCA has completed the first Executor engine

ARCA completed the work on the first Executor Engine, designed for the Haas 2C rocket and Excelsior rocket-plane. A second Executor engine is 50% completed. The Executor engine uses liquid oxygen as oxidizer and and kerosene as fuel. The engine has a thrust of 53,000 lbf (24,000 kgf) in vacuum and has a maximum operating time of 190 seconds. By using composite materials and aluminum alloys on a large scale, Executor engine weights only 210 kg, and has a thrust to weight ratio of 110. ARCA estimates achieving an even better ratio after the tests are completed.





June 1, 2012 - The Haas 2C orbital rocket

ARCA presented the Haas 2C orbital rocket. The rocket have launch weight of 35,000 lb (16,000 kg) and is designed to place 880 lb (400 kg) into LEO. Haas 2C first payload will be the CubeMessenger, the next Bulgarian satellite. CubeMessenger, built by Bulgarian team BOREAS (Bulgarian Orbital Research and Satellites), is a satellite with an operational lifespan between one week and a month. It will be used to test and refine available communications and attitude control instrumentation and to provide a practical experience in small satellite operation. CubeMessenger will be equipped with a digital camera for Low Earth Orbit observations.





March 27, 2012 - The best rocket fuel tank in the world

ARCA tested the kerosene tank for the Excelsior rocket-plane and Haas 2 orbital rocket. The team pressurized the tank beyond its strength limit. The tank walls are so thin that the tank must be maintained at an internal pressure of 0.5 atmospheres, even during storage. If the pressure were removed from the tank, it would collapse under its own weight. The ratio of structure mass / fuel mass / pressure is 0.00082, the best ever in aerospace industry. The tank, which will be used for the Google Lunar X Prize competition, was made entirely from composite materials. "Sunday's test has confirmed that we are the owners of the technology to fabricate the lightest kerosene rocket tanks in the world, which will be used during the incoming flights. We succeeded to outperform the Atlas and Centaur rocket fuel tanks, known as the lighter tanks. This technology will be implemented on the Excelsior rocketplane and Haas 2 rocket. I want to congratulate the team for the exceptional result." - Dumitru Popescu, ARCA President.





March 5, 2012 - The combustion chamber and nozzle for the first Executor engine have been completed

ARCA completed the work on the combustion chamber and nozzle of the first Executor engine for the IAR-111 Excelsior rocket-plane and the Haas 2C orbital rocket.
The structure is made of two main layers: an internal layer for thermal protection made of silica fiber and phenolic resin, and an external layer able to support the structural load, made of carbon fiber and epoxy resin. Executor is an open cycle engine, with a gas generator, that uses liquid oxygen and kerosene and has a vacuum thrust of 52,000 lbf (24,000 kgf).
