هذه المقالة عن القطار، وهو وسيلة نقل. لمعانٍ أخرى، طالع قطار (توضيح).
وہ فرشتہ جسے اﷲ تعالیٰ سے بہت قربت حاصل ہو ؛ جیسے : عزرائیل ؑ، اسرائیل ؑ، میکائیل ؑ یا جبرئیل ؑ۔ ی
والقطار يسير على عجلات من الحديد الصلب، ويتكون من قاطرة في المقدمة عبارة عن محرك قوي تقوم بجر عربات الركاب أو عربات البضائع خلفه؛ العربات أيضاً ترتكز على عجلات من الحديد الصلب.
The wing planform is the shape when viewed from above. For being aerodynamically successful, a wing need to be straight having a extended span back and forth but have a short chord (higher aspect ratio).
Some varieties use turbine engines to travel a propeller in the form of the turboprop or propfan. Human-driven flight continues to be obtained, but hasn't become a realistic implies of transportation. Unmanned aircraft and styles have also employed power sources like electrical motors and rubber bands. Jet plane[edit]
A handful of experimental designs rely completely on motor thrust to offer carry all over the complete flight, including individual enthusiast-lift hover platforms and jetpacks. VTOL analysis designs include the Rolls-Royce Thrust Measuring Rig.
A traveling wing has no fuselage, even though it may have little blisters or pods. The alternative of this can be a lifting physique, that has no wings, though it could have modest stabilizing and control surfaces.
Pitch is a rotation about the sideways horizontal axis supplying an up-down motion from the aircraft nose measured by the angle of attack.

Airplanes have complicated flight control devices. The key controls allow the pilot to direct the aircraft within the air by controlling the Frame of mind (roll, pitch and yaw) and engine thrust.
Airframe diagram for an AgustaWestland AW101 helicopter Heavier-than-air varieties are characterised by a number of wings and a central fuselage. The fuselage normally also carries a tail or empennage for check here steadiness and Handle, and an undercarriage for takeoff and landing. Engines may be located within the fuselage or wings.
Variants on the jet motor contain the ramjet and the scramjet, which depend upon significant airspeed and intake geometry to compress the combustion air, prior to the introduction and ignition of gas. Rocket motors give thrust by burning a gas having an oxidizer and expelling fuel through a nozzle.
