its 90 degrees!

new cryptid/monster: The Harvestman. 

A humanoid figure covered head to toe in what appears to be coarse fur, at first glance very similar similar to bigfoot/sasquatch. However on closer inspection it is comprised of millions and millions of Harvestmen/Daddy long Legs (MAJOR insect/cluster warning for that link). 

Will scatter into an inhuman mass when surprised or disturbed, only to reconstitute somewhere else. If given space in a calm setting, will behave in an oddly human way, walking around, exploring it’s environment, finding cold/dark places to hide. If approached very carefully, may even be capable of communication…

When you are in the combat zone, agility of a fighter jet is of utmost importance. But as an engineer, if you have already fiddled around with the wing structure your next option would be to fiddle around with the direction of the thrust.

Thrust Vectoring

Thrust vectoring is primarily used for directional control in rockets and jets. And one achieves this by manipulating the direction of thrust .

This generates the necessary moments (and forces) that enable the directional control of the aircraft. 

An aircraft traditionally has three “degrees of freedom” in aerodynamic maneuverability; pitch, yaw and roll. **

The number of “dimensions” of thrust vectoring relates directly to how many degrees of freedom can be manipulated using only the vectored engine thrust.

Therefore, 2D vectoring allows control over two degrees of freedom (typically pitch plus either roll or yaw) while 3D controls all three.



Lockheed Martin F35B

The F-35B short takeoff/vertical landing (STOVL) variant is the world’s first supersonic STOVL stealth aircraft.

It achieves STOVL by swiveling its engine 90 degrees and directing its thrust downward during take off/lvertical landing mode.

In the following gif you can witness the transition from a 90 degree tilted engine towards a forward thrust engine during flying.

Unlike other variants of the Lockheed Martin F-35 the F-35B has no landing hook. And as a result, witnessing its landing is rather pretty special.

But nevertheless, this is one of those posts which addresses a topic that has been a gold mine for research. If this sort of thing fascinated you, there have been a lot of research conducted by NASA do check them out.

Have a great day!

Ooh yes yes… i love neck kisses ;; this is a BIG big big weakness for Kumi hehe. I finally got around to do one of the suggestions! I want to do more now but now ive got some commissions and a trade to do so i will do more later ^^ I dont mind ya’ll sending some more over in the meantime tho ;w;
