A vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) [1] or a rotor blade of a wind turbine. [2] VGs may also be attached to some part of an aerodynamic vehicle such as an aircraft fuselage or a car.
The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The gas emerging from the hot end can reach temperatures of 200 °C (390 °F), and the gas emerging from the cold end can reach −50 °C (−60 °F). [ 1 ]

The main electrical system on the B.1/B.1A was 112 V DC supplied by four 22.5kW engine-driven starter-generators. Backup power was provided by four 24 V 40 Ah batteries connected in series providing 96 V. Secondary electrical systems were 28 V DC, single-phase 115 V AC at 1600 Hz, and three-phase 115 V AC at 400 Hz, driven by transformers and ...
This includes 100 to 120 nmi range increase, [58] and a 45 kg (99 lb) MTOW increase and take-off run reduction by 135 m (443 ft) to 1,064 m (3,491 ft); this is achieved by an extending the span of the horizontal tailplane by a few inches, and by removing wing fences and vortex generators. [59]
The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle.

The green vortex generators prompt the transition to turbulent flow and prevent back-flow also called flow separation from the high-pressure region in the back. The surface in front is as smooth as possible or even employs shark-like skin, as any turbulence here increases the energy of the airflow.
