High-Accuracy Entry Guidance with Analytical Trajectory Prediction for Large-Maneuver Gliding
Publisher: American Society of Civil Engineers
Abstract: AbstractIn hypersonic vehicle entry guidance, trajectory prediction is widely used, and its
accuracy directly affects the performance of the flight mission. To fast predict the
trajectory, existing methods mainly focus on ...
What Kinds of Atmospheric Anomalies Drive Wintertime North Pacific Basin-Scale Subtropical Oceanic Front Intensity Variation?
Publisher: American Meteorological Society
Abstract: The basin-scale subtropical oceanic front zone (STFZ) is a key region for midlatitude air–sea interaction in the North Pacific. However, previous studies considered midlatitude sea surface temperature (SST) variabilities ...
The Meridional Shift of the Midlatitude Westerlies over Arid Central Asia during the Past 21 000 Years Based on the TraCE-21ka Simulations
Publisher: American Meteorological Society
Abstract: To advance our knowledge of the response of midlatitude westerlies to various external forcings, we investigate the meridional shift of midlatitude westerlies over arid central Asia (ACA) during the past 21 000 years, which ...
QPSO-BP Neural Network Model for Actuator Pressure and Friction Torque in Solid Rocket Ball Joint Nozzles
Publisher: American Society of Civil Engineers
Abstract: AbstractFriction torque is crucial to the overall design, reliability of motion, and accuracy
of a rocket nozzle. The accurate prediction of driving pressure is essential for calculating
the friction torque. To address ...
Mechanism of Liquid Nitrogen Freezing–Blasting Synergistic Fracturing for Coal Seam Permeability Enhancement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. To enhance gas extraction from low-permeability coal seams, this study introduces a synergistic liquid nitrogen (LN2) freezing–blasting method designed to mechanically precondition coal and promote fracture ...
Thermal Storage Stability of Bio-Oil Modified Asphalt
Publisher: American Society of Civil Engineers
Abstract: This study investigates and evaluates the storage stability of asphalt binder modified by bio-oil at high temperature. Five bio-asphalts are prepared by adding 1, 15, 2, 25, and 3% bio-oil into 7# petroleum asphalt. The ...
Vertical Variability of the Raindrop Size Distribution in Typhoons Observed at the Shenzhen 356-m Meteorological Tower
Publisher: American Meteorological Society
Abstract: Raindrop size distribution (DSD) characteristics at various altitudes in two landfalling typhoons in 2017 (Hato and Pakhar) were investigated by using laser optical disdrometers mounted at four altitudes (10 m, 40 m, 160 ...
Adhesion Mechanism and Interfacial Failure Behavior of Castor Oil–Based Bioasphalt and Aggregate under Thermal Oxidation
Publisher: American Society of Civil Engineers
Abstract: AbstractThe objective of this research is to investigate the degradation mechanism of adhesion
and interfacial failure behavior between bioasphalt and aggregate under the action
of thermal oxidation. This study investigates ...
