Steering Air Craft at Sea

WIG-craft Marine Landing Control at Rough Sea

Wing-in-Ground Effect vehicle (WIG-craft) or ekranoplane landing direction optimization criteria is suggested which heeds the irregular sea waves features and provides the minimal mechanical strain on the vehicle body at hydrodynamic braking. The problem of automatic choice of the landing trajectory direction regarding the main direction of sea waves spread is under consideration. The peculiari...

Lighter than Air Craft Using Vacuum

Ever since his earliest times, man must have dreamed of copying the birds; of flying, of gaining mastery over the third dimension of space. The earliest practicable route to achieve the aim of flying was in the use of balloons. The first balloons were hot-air balloons; they relied on the lower density of hot air, compared to that of the surrounding air, to obtain the lift they needed. Balloons ...

Physics-based Parameterizations of Air-sea Fluxes at High Winds

The long term goal of this project is to provide a new set of parameterizations of air-sea fluxes, which can be used as boundary conditions for high-resolution numerical models of ocean, atmosphere, and coupled ocean/atmosphere systems. The new parameterizations will be constructed based on physical processes of the exchange of mass, momentum, heat, moisture, energy at the interface between the...

Biopolymers form a gelatinous microlayer at the air-sea interface when Arctic sea ice melts

The interface layer between ocean and atmosphere is only a couple of micrometers thick but plays a critical role in climate relevant processes, including the air-sea exchange of gas and heat and the emission of primary organic aerosols (POA). Recent findings suggest that low-level cloud formation above the Arctic Ocean may be linked to organic polymers produced by marine microorganisms. Sea ice...
