The advanced sensors require onboard processing of signals in a dedicated Data Handling Unit prior to transmission to the vehicle via an RS interface. As an experimental vehicle primarily intended to gather data, various assorted sensors and monitoring equipment are present and operational throughout the full length of the flight in order to gather data to support the evaluation effort, including the verification of the vehicle’s critical reentry technologies. European Space Agency officials are already planning the spacecraft’s next test. The flow control valves of each thruster are operated on command from the onboard computer through an RS link. As the IXV spaceplane descended, it maneuvered to decelerate from hypersonic to supersonic speed. These three avionic subsystems interface with the following subsystems:. This link had been recently changed by the Satellite provider and a loose cable in an interconnection rack led to the high loss of frames.

Following the drop-test, the vehicle was retrieved for further analysis. The Materials Catalytic Behavior Experiment studies dissociation-recombination processes occurring within the boundary layer formed on the heat shield in a highly dissociated flow.
The final chute utilizes reefing stages to reduce the maximum force acting on the vehicle to 3. The brain of the spacecraft is a central Onboard Computer using a LEON-2 microprocessor that is in charge of the execution of the flight software and the control of all mission tasks. The thrusters are used to provide three-axis control during orbital flight and yaw control through the re-entry process while also complementing the two aerodynamic flaps in controlling the pitch and roll during re-entry.
The flow of heat across these panels will be mapped for the first time, by an infrared camera and sensors spanning the spacecraft from nose to flaps.
The overall architecture of the experiment system installed on IXV consists of two segments — conventional sensors such as thermocouples, pressure sensors, stain gauges and displacement sensors, and advanced sensors comprised of an infrared camera.
Intermediate eXperimental Vehicle
This is achieved through the use of data from the various thermocouples in the windward assembly as well as the IR camera at the base of the vehicle. Special operators had to be enrolled and trained. The sensors are arranged in a cross array in order to maximize gradient readings. The Ground Communications Network had to account also for the data and voice links required to support ix operations. Its hypersonic lift-to-drag ratio of 0.
Note that the white color is due to the accumulation of salt resulting from the immersion in sea water after splashdown.
See templates for discussion to help reach a consensus. The hardware will be removed for engineers to evaluate the reusability of components and the effects of heat, pressure and shock during the mission.
Europe’s Newly Tested Space Plane Aims for Next Launch in 2019
The thrusters are fed from a single titanium tank ixb propellant lines including pyrotechnic latch valves. Timing data is provided to the OBC by means of a 1 Pulse Per Second signal with a nano-second accuracy while position data is delivered at a frequency of 1Hz via a serial RS link. Each sensor integrates a Linear Variable Differential Transformer-type sensor in an aluminum housing with a stroking element made of ceramic material with low thermal conductivity and extremely low thermal expansion.
Illustration of the windward TPS image credit: All in all, IXV hosts Type-S Platinum thermocouples, 89 Type-K iv, 37 absolute pressure sensors, 2 differential pressure sensors, 12 displacement sensors, 48 strain gauges and one Infrared Camera System.
The Preliminary Design Review was passed, however, the project was set back somewhat by a number of redesigns that were necessary due to changes in the industrial organization at the prime and subcontractor levels. The General Heating Experiment investigates the evolution of global heating at the surface of the vehicle during the hypersonic phase of the re-entry which covers the continuous flow plus laminar and turbulent regimes.
The Gaps and Cavity Heating experiment examines the local aerothermodynamics in cavities and potential sneak flows that could be induced by pressure gradients under imperfect sealing.
The focus of activity on flight day will be the MCC, housed at the Advanced Logistics Technology Engineering Center, in Turin, Italy, which will coordinate the entire ground segment, including the 10 m diameter dishes in Libreville Gabon and Malindi Kenyaand the tracking antenna on the recovery ship, Nos Aries.
The vehicle purposefully includes several key technologies of interest to the ESA, including its thermal protection system and the presence of active aerodynamic control surfaces.
As the IXV spaceplane descended, it maneuvered to decelerate from hypersonic to supersonic speed. The ground segment comprises the mission control systems, data networks and tracking stations that support a spacecraft in flight. It was designed and developed to support data, voice and video transmission. Each bag has a volume of 0. The minimum battery voltage observed from test was During Junethe IXV test vehicle arrived at the ESTEC Technical Centre in Noordwijkthe Netherlands, to undergo a test campaign to confirm its flight readiness in anticipation of a flight on a Vega rocketwhich was by that point scheduled to occurring during November of that year.
One of the IXV mission success criteria was the collection and recovery of exploitable flight data and this objective was the driving factor behind requirements for the IXV data handling subsystem. Flaps and thrusters will autonomously steer it back to a splashdown at a precise point in the Pacific Ocean.

Herakles-Safran The TPS concept is based on the “shingle design”, which dissociates thermal and mechanical functions. This subsystem is the key element behind the complex and autonomous IXV operations.
Retrieved 16 November The experiment consists of several thermocouples with pressure data being used from the continuous and base flow experiments.
