Introduction to Spacecraft Thermal Design (Cambridge

Convection The fundamental relationship used to model thermal energy exchange between a fluid (either liquid or vapor phase) and a surface is Newton's law of cooling. This relationship is shown in equation 1.4 and illustrated in Figure 1.4. Q_ hconv A T surf Tl

Highly humid conditions may make the situation worse. For pulse (trigger) type starters, there may be too much capacitance as well. In the case of an enclosed laser head with a HV (e.g, Alden) connector, HV cable, and internal (potted) ballast resistor, there may be a breakdown in one of these components and it may only show up when starting voltage is applied (not with an ohmmeter).

1989 NASA SBIR STTR Abstract Archives

Thermal-barrier coating applied to housings of rotary engines reduce engine heat rejection, improve thermal efficiency and reduce cooling requirements. However, recent tests indicate that a thermal-barrier coating on the side housing of an air-cooled rotary engine results in surface temperatures beyond the capability of conventional hydrocarbon lubricants.

It can be used in the Auto Thermal Reformer (ATR) of a Solid Oxide Fuel Cell (SOFC) for the auxiliary power unit (APU) in an aircraft. The sprays generated from this mixer/injector are extremely fine and uniform, which is great for gas-turbine-combustor or industrial-burner applications for

Global Solid Oxide Fuel Cell (SOFC) market will reach 1080 million

Categorization on the basis of technology includes tubular, planar and other SOFCs. Planar SOFC have the largest market demand on account of higher power ratio as compared to other SOFCs, despite high installation costs. Planar SOFC has the highest electrical efficiency that allows great potential for applications in military, leading to higher demand in the aforementioned application.

We propose a 1.5um fiber-optic pulsed coherent lidar as a highly effective sensor sub-system for airborne wake-vortex hazard detection. The proposed design is based on a recently developed platform at Fibertek, for fiber-optic pulsed coherent lidar capable of 6km range, and operating at high pulse rate to give high-resolution spatial map and circulation strength, characteristic of typical wake

Review of Scientific Instruments via MedWorm

When a reference thermal source is used forcalibration, the spectrometer can function as a fast opticalpyrometer. Applications of the spectrometer are illustrated by using it to capture single-shot emission transients from energeticmaterials or reactivematerials initiated by km ⋅s−1impacts with laser-driven flyer plates.

US Patent for Privacy and security systems and methods

For example, in some embodiments, the vibration isolation cage can be coupled to an inner surface of the privacy/security enclosure using a coupler comprising an elastomeric material. In other embodiments, the coupler can comprised a fluid-filled chamber in which the fluid is selected for its attenuation of certain vibration frequency ranges.
