Flight measured and calculated exhaust jet conditions for an F100 engine in an F-15 airplane [PDF]
The exhaust jet conditions, in terms of temperature and Mach number, were determined for a nozzle-aft end acoustic study flown on an F-15 aircraft. Jet properties for the F100 EMD engines were calculated using the engine manufacturer's specification deck.

Morphology and Mach Number Dependence of Subsonic Bondi–Hoyle Accretion
The Astrophysical JournalWe carry out three-dimensional computations of the accretion rate onto an object (of size R _sink and mass m ) as it moves through a uniform medium at a subsonic speed v _∞ . The object is treated as a fully absorbing boundary (e.g., a black hole).

Laser &Photonics Reviews, EarlyView.This work presents a novel technique to control photonic accelerators based on integrated Mach–Zehnder interferometers, enabling resolutions of 7.01 and 8.04 bits for the output power and phase setting. The technique uses local feedback loops that ensure precise calibration‐free programming of the device transfer function, enabling highly accurate ...

Tunable Topological Directional Supercoupler and Applications in THz On‐Chip Communication
Laser &Photonics Reviews, EarlyView.A topological directional supercoupler is demonstrated, enabling dual‐channel 50 Gbps on‐chip terahertz communication with phototunable power splitting ratios. The achieved sub‐wavelength scale coupling area, sharp waveguide bends, and momentum‐conserved coupling process allow for ultra‐compact and efficient terahertz topological photonic integrated ...
