Abstract EN
For atmospheric reentries at high enthalpies ablative heat shield materials are used, such as those for probes entering the atmosphere of Saturn’s moon Titan, such as Cassini-Huygens in December, 2004.
The characterization of such materials in a nitrogen/methane atmosphere is of interest.
A European ablative material, AQ60, has been investigated in plasma wind tunnel tests at the IRS plasma wind tunnel PWK1 using the magnetoplasma dynamic generator RD5 as plasma source in a nitrogen/methane atmosphere.
The dimensions of the samples are 45 mm in length with a diameter of 39 mm.
The actual ablator has a thickness of 40 mm.
The ablator is mounted on an aluminium substructure.
The experiments were conducted at two different heat flux regimes, 1.4 MW/m2 and 0.3 MW/m2.
In this paper, results of emission spectroscopy at these plasma conditions in terms of plasma species’ temperatures will be presented, including the investigation of the free-stream species, N2 and N2+, and the major erosion product C2, at a wavelength range around 500 nm–600 nm.
