In April 2021, the developers announced plans to launch a Kickstarter project later in the month to turn the demo into a full game. [12] On April 18, a Kickstarter project for the full version of the game was released under the name Friday Night Funkin': The Full Ass Game and reached its goal of $60,000 within hours. [18]
The high-bypass turbofan engines used on many modern airliners is an example of a very successful and popular use of ducted fan design. The duct increases thrust efficiency by up to 90% in most cases [citation needed], in comparison to a similar-sized propeller in free air. Ducted fans are quieter, and offer good opportunities for thrust vectoring.
The two are related by the propulsive efficiency, [66] a measure of the energy wasted as a result of producing a force (ie thrust) in a fluid by increasing the speed (ie momentum) of the fluid.

The higher-thrust variants, GE90-110B1 and -115B, have a different architecture from that of the earlier GE90 versions. General Electric incorporated an advanced larger diameter fan made from composite materials which enhanced thrust at low flight speeds. However, GE also needed to increase core power to improve net thrust at high flight speeds.
The thrust force from a stationary engine becomes thrust power when an aircraft is moving under its influence. Zhemchuzhin et al. [27] show an energy balance for a turbojet engine in flight in the form of a Sankey diagram. Component losses leave the engine as waste heat and add to the heat rejected area on a T~s diagram reducing the work area ...
The F-35B uses both a lift-fan and vectors engine thrust down. A lift jet is a lightweight jet engine used to provide vertical thrust for VTOL operation, and is then shut down in forward flight. Some VTOL designs, including the Soviet Yakovlev Yak-38 and Yakovlev Yak-141 , have used both vectored thrust from the main engine and additional ...
The General Electric F414 is an American afterburning turbofan engine in the 22,000-pound (98 kN) thrust class produced by GE Aerospace (formerly GE Aviation). The F414 originated from GE's widely used F404 turbofan, enlarged and improved for use in the Boeing F/A-18E/F Super Hornet.
