A Data‐Driven Approach to Integrated Adaptive Morphing and Guidance for Cruise Missiles
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT To address the complex coupling between aerodynamic characteristics and guidance control for morphing flight missiles, this study proposes a data‐driven approach to integrated adaptive morphing and guidance. Firstly, an aerodynamic surrogate model is constructed using a fully connected neural network (FCNN), mapping the configuration ...

Noise suppression with high Mach number inlets [PDF]
Experimental results were obtained for two types of high Mach number inlets, one with a translating centerbody and a fixed geometry inlet (collapsing cowl) with no centerbody. The aerodynamic and acoustic performance of these inlets was examined.

Refuge trifecta: intertidal gastropods use pits to escape heat, wave action and predation
Oikos, EarlyView.Refuges play a critical role in ecology and evolution. In hard intertidal shores, small pits attract benthic invertebrates such as gastropods, however, there exists little mechanistic understanding of the processes driving the active usage of these microhabitat features. We conducted a series of laboratory experiments to assess whether the marine snail

Ground Measurements of Airplane Shock-Wave Noise at Mach Numbers to 2.0 and at Altitudes to 60,000 Feet [PDF]
The intensity of shock-wave noise at the ground resulting from flights at Mach numbers to 2.0 and altitudes to 60,000 feet was measured. Meagurements near the ground track for flights of a supersonic fighter and one flight of a supersonic bomber are ...

High Reynolds Number Test of the Boeing TR77 Airfoil in the Langley 0.3-Meter Transonic Cryogenic Tunnel [PDF]
A Boeing TR77 airfoil associated with the Advanced Technology Airfoil Test (ATAT) program was tested in the Langley 0.3 m Transonic Cryogenic Tunnel. Limited analysis of the data indicated that increasing Reynolds number for a fixed Mach number resulted ...

Jet-edge interaction tones [PDF]
, 2017 Motivated by the problem of jet-flap interaction noise, we study the tonal dynamics that occur when a sharp edge is placed in the hydrodynamic nearfield of an isothermal turbulent jet.
