Entry Guidance Authority over Thermal Protection System Bondline Temperature

Thermal protection systems are sized against the temperature of the structure beneath them, yet entry guidance enforces heating rate, heat load and load factor and leaves structural temperature to offline margins. This paper asks how much guidance can do about the bondline temper...

Seed variability and calibrated error bounds for physics-informed conjugate heat transfer surrogates

Physics-informed neural networks are often proposed as fast surrogates for heat transfer problems too expensive to solve inside a design or control loop. Two questionsabout them are rarely answered: how much of the reported accuracy survives a change of random seed, and how large...
