Instead, the Chinese fire control radar for J-7G is developed from EL/M-2032 fire control radar China obtained from Israel when it was a subcontractor for Elbit in the Romanian MiG-21 LanceR program described above. [74] [75] J-7G: Upgraded J-7E with more than 30 improvements with Mr. Song Cheng-Zhi (宋承志) as the general designer.

The ram-air inlet is a small scoop, generally located on the wing-to-body fairing. Nearly all jetliners use a modulating door on the ram-air inlet to control the amount of cooling airflow through the primary and secondary ram air heat exchangers. To increase ram-air recovery, nearly all jetliners use modulating vanes on the ram-air exhaust.
Four wires come to the centrally-located thermostat from the main heating/cooling unit (usually located in a closet, basement, or occasionally in the attic): One wire, usually red, supplies 24 volts AC power to the thermostat, while the other three supply control signals from the thermostat, usually white for heat, yellow for cooling, and green ...
This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to ...

Elon Musk's lawyers faced off with OpenAI in court Tuesday as a federal judge weighed the billionaire's request for a court order that would block the ChatGPT maker from converting itself to a for ...
For example, the same helicopter weight can be supported by a high power engine and small diameter rotor or, for less fuel, a lower power engine and bigger rotor with lower velocity through the rotor. Bypass usually refers to transferring gas power from a gas turbine to a bypass stream of air to reduce fuel consumption and jet noise.
