Abstract

An arc-jet test campaign is used as a baseline to computationally model the flow and material response of cavities. A parametric study is designed around the baseline to study geometric effects on parameters of interest. The US3D flow solver is used to simulate the arc-jet flow in the Aerodynamic Heating Facility (AHF) at NASA Ames and generate the heating environment over material samples with cavities. The Icarus material response code is then used to simulate the multi-dimensional heating under the above conditions of samples of FiberForm with cavities.

Dragonfly: A Case Study in Dynamic Stability Characterization

Next decade, the Dragonfly probe will enter Titan’s atmosphere on a mission to explore and characterize its unique and complex organic chemistry. In contrast to Mars entry missions, where the challenge is to slow down in its tenuous atmosphere before impacting the surface, Titan’s thick atmosphere provides generous drag. However, Titan has its own unique EDL challenges. Among these challenges is the long time (on the order of 90 minutes!) the vehicle will need to descend unguided through flow regimes where blunt-body entry probes are known to be dynamically unstable. This elongated timeline, both prior to drogue parachute deployment, and during the ensuing descent, has the potential to allow adverse dynamic instability properties to produce large amplitude oscillations in angle-of-attack. This, in-turn may lead to non-compliance in vehicle attitude requirements for EDL events such as parachute deployment, and lander release, or in the most extreme case, tumbling of the aeroshell and near-assured loss of mission.

Entry, Descent, and Landing Instrumentation

Overview of sensors used in EDL instrumentation suites. For spaceflight missions involving atmospheric entry, the environment experienced by a spacecraft cannot be fully replicated on the ground. Taking measurements in the flight environment is the “gold standard” for: Validating predictive modeling tools Reducing risk on future EDL missions EDL Instrumentation can consist of in-situ sensors embedded within the aeroshell, or remote observations. Focus of this presentation is on NASA in-situ sensors.
