The Verner VM 133 is a family of Czech two cylinder, horizontally opposed, four stroke aircraft engines, designed and built by Verner Motor of Šumperk. [ 1 ] [ 2 ] [ 3 ] Design and development
Spiral slipstream, also known as propwash, prop wash, or spiraling slipstream, is a spiral-shaped slipstream formed behind a rotating propeller on an aircraft. The most noticeable effect resulting from the formation of a spiral slipstream is the tendency to yaw nose-left at low speed and full throttle (in centerline tractor aircraft with a ...
Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...
A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller thrust , thereby giving rise ...
Deflected slipstream is an approach to creating an aircraft that can take off and land vertically (), or at least with a very short runway ().The basic principle is to deflect the slipstream from one or more propellers approximately 90 degrees, to create an upward thrust for vertical takeoff and a downward air cushion for landing.
D-CAAA to D-CZZZ for aircraft with 5.7–14 t MTOW; D-EAAA to D-EZZZ for single-engine aircraft up to 2 t MTOW; D-FAAA to D-FZZZ for single-engine aircraft with 2–5.7 t MTOW; D-GAAA to D-GZZZ for multi-engine aircraft up to 2 t MTOW; D-HAAA to D-HZZZ for rotorcraft; D-IAAA to D-IZZZ for multi-engine aircraft with 2–5.7 t MTOW
Meanwhile, the first time that ETOPS-330 approval was given to a four-engine aircraft was in February 2015, to the Boeing 747-8 Intercontinental. [15] It is the only ETOPS-compliant aircraft allowed to run non-stop overflights over Antarctica with proper alternates, alongside the Airbus A340 and A380. [citation needed]
