Centauro (sounding rocket)

Last updated

The Centauro series is a family of Argentinian solid-fuel sounding rockets developed by the Instituto de Investigaciones Aeronauticas y Espaciales (IIAE). This family includes Alfa, Beta, and Gamma Centauro. [1] [2] [3]

Contents

Alfa Centauro was a single-stage rocket, launched in 1961 from Santo Tomás base.

Beta Centauro followed the same year, demonstrating two-stage capability and leading to advancements in payload delivery and high altitude measurements. Further launches from Santo Tomás and CELPA Chamical refined rocketry techniques. Notably, the "sodium cloud" operation in 1963 provided valuable atmospheric data.

The Gamma Centauro, also a two-stage vehicle, was tested after 1964, notably from Antarctica. [4]

Flights

The first launch took place on February 2, 1961, [6] [7] [8] from the Santo Tomás base in the Achala Pampa in the province of Córdoba. [9] [10] [11] The rocket was named APEX A1-02 and reached an altitude of 20 km. [10] [11] [12]

Beta Centauro, a two-stage sounding rocket, had a length of 3,812 mm. The first stage (similar to Alfa Centauro) measured 1,769 mm with a diameter of 94 mm, and the second stage was 1,173 mm long with 79.5 mm in diameter. [5]

Main characteristics of the Beta Centauro sounding rocket were: [5]

Flights

Beta Centauro was first launched on September 30, 1961. The rocket as designated APEX-A1-S2-015 and aimed to experiment with the separation of the two stages and to test the measurements and instruments of the vehicle: flight speed, range, atmospheric pressure, among other parameters. [13] [5] The launch was successful, and the rocket reached an altitude of 25 km. [6]

On October 13, 1961, the Aerospace Institute conducted the second launch of the rocket (APEX-A1-S2-016) at the same base. [5] [9] Another Centauro rocket was launched on May 10, 1962, coinciding with the start of activities at the CELPA base in Chamical, La Rioja.

On February 19, 1962, five new launches were carried out from the Santo Tomás Base, where the new Scar 2.65 engines were tested for the first time, successfully recovering the capsules with their payloads in all cases, allowing the measurement of the altitude at which the separation occurred. [14]

On November 15, 27, and 30, Centauro rockets were launched, the last two for aeronomy purposes, all three launched from the CELPA Chamical base, La Rioja province. [9] On December 8 and 9, Centauro rockets were launched again, also for aeronomy purposes and with successful results. Throughout that year, the experiments were successful and yielded significant advances, with a total of 18 launches carried out. [9]

On May 25, 1963, the Centauro 35 launch was undertaken for the "sodium cloud" operation, resulting in wind and turbulence measurements, reaching an altitude of 189 km. [9]

Experiments with the Beta Centauro allowed for the refinement of payload takeoff and altitude measurements, continuing from 1964 with the Orion sounding rocket. [14]

Gamma Centauro was a two-stage rocket, with a length of 2.43 m and a diameter of 13 cm, capable of sending a 5 kg payload to an apogee of 59 km. [2]

Details

Main characteristics of the Gamma Centauro sounding rocket were: [2] [15] [16]

Flights

Gamma Centauro was first tested on December 6, 1962. [2] The following year, several tests of models I and II were conducted at CELPA. [17]

On August 27, 1964, the "Operation Inca" mission was carried out in the province of Mendoza (more precisely near the Puente del Inca). During the operation, a vehicle was propelled to an altitude of 35 km, and the payload was recovered by parachute. The model served to test the equipment that would later be part of the next project in Antarctica in 1965, including the launch tower and the polyethylene cover with heating that maintained the cabin at a temperature of 25 °C. [17]

Gamma Centaur tests continued in February 1965 when, for the first time, two Gamma Centaur rockets were simultaneously launched from the CELPA Experimentation Center, and two others from the Matienzo Base in Antarctica. [2] [4] [18] [19] Two sounding balloons assembled by the National University of Tucumán were also tested, reaching an altitude of 24 km.

In this way, Argentina became the third country, after the Soviet Union and the United States, to undertake aerospace activities from Antarctica. [17] The resulting experiences were used to analyze flight and study X-rays in the atmosphere. In August, four tests were carried out with Gamma Centauro rockets from the CELPA base, all successful.
