Drop it like it’s hot: Space Rider model falls gracefully

During the last 4 months, the House Rider workforce has been working a drop-test marketing campaign whereby a full-scale mannequin of the longer term orbital laboratory is dropped from a helicopter to check and qualify the deployment of its parachutes, at Salto di Quirra in Sardinia, Italy.

The House Rider challenge is an uncrewed laboratory in regards to the measurement of two minivans that can have the ability to keep in orbit for as much as two months. The spacecraft is available in two elements, an orbital module that provides every thing it must fly round our planet and a reentry module that brings House Rider and its experiments again to Earth.

Over the course of this check marketing campaign that began in April and is anticipated to complete in autumn, the groups are utilizing a mannequin of House Rider that has an identical weight distribution as the true 3,000 kg reentry module. This enables the workforce to check the parachutes, parafoil and management winches that robotically information the spacecraft to a comfortable landing on Earth.

Dropped from a maximum height of three.5 km, drogue chutes deploy to assist decelerate the test model to a protected pace to extract the parafoil that can permit the spacecraft to be steered to a touchdown strip. The large paraglider is 27 m lengthy and 10 m extensive—round 10 occasions bigger than a human parafoil—and is managed from the bottom to check the aerodynamics concerned. The check mannequin touched down in a soft landing as deliberate, shedding altitude at a sluggish 12 km/h.

In autumn, the identical full-scale mannequin will bear extra flight tests, together with a check of the flight management algorithm that can information the spacecraft mannequin by itself to land at a specific touchdown level—no extra ground control, however full automation for the following step of the check marketing campaign. This step will additional affirm the engineering and software program behind this novel spacecraft.

Thales Alenia House is the commercial lead for the checks and co-prime for the House Rider program. The Italian Protection helps the check actions as a part of a nationwide effort to boost its space capabilities and worldwide collaboration within the sector. The checks will qualify the spacecraft’s entire mission from flight, return to Earth, and touchdown. After the check campaigns, flight fashions will probably be approved for manufacturing.
