Flight-by-light for JF-17: A possibility in the futur

[The SC]

Abstract
—
In past, the aircraft control systems were based on conventional methods of mechanical and hydro-
mechanical system. The present generation aircraft are using fly-by-wire (FBW) and in future likely to migrate to fly-by-light (FBL) method for aircraft control system.
Mechanical & Hydro-mechanical flight control systems have been replaced by Fly-By-Wire due to increasing speed of modern aircraft.
Due to inherent characteristics of FBL like light weight, compact size, large bandwidth, immunity to EMI & HIRFFBL , it is expected to be ideal futuristic flight control system.
Fly-by-Light control systems offer inherent resistance to the new generation more hostile military environments. The inherent features are the motivator to achieve the technological advances to make Fly-by-Light systems a successful replacement aircraft control system technology for future.
The application of optical fiber in aviation promises to be very exciting study, covering highly complex aircraft stability and controls.

The application of optical fiber in aviation promises to be very exciting study, covering highly complex aircraft stability and controls.

A very good approach in making in the world for replacement of FBW system. I have one query in this regard that though commands from stick movement would be converted into signals and moved through OF but the end execution would most probably be same as Electro-Hydro-Mech or combination of any two. Am i right in this regard or with FBL the execution part would also be revolutionized?
Thanks in advance.

i guess it will be automatic as it is now with full FBW

My Mercedes has dual redundant MOST based fiber rings.

And JF17 is a warplane.

That's a great development and PAF should be looking to incorporate this in the next block of JF-17s and also explore the options to retrofit the earlier versions of JF-17 with FBL system.

Fly by wire does not remove the control surface. It only reduces the tension that was felt on the controls when they were mechanically controlled.
Aircraft still use mechanical linkage but are operated through electrical inputs rather than human force.

It is an automatically assisted control, just like the assisted stearing in a big and modern Automobile, I drove 2 of these it is very sensitive, but one gets used to it rather quickly..

Good to know a simple Actuator in there

What's -future -likely to and so on?
Check out the Rafale A, that Blue White and Red original demonstrator : FBL, all optic fibers!
CDVO = optical flight commands.
Dassault may or may not have it on the series planes, they're very discreet on that but the FCS
is one of their priorities that they refuse to delegate even though SAGEM is renowned for these
in civilian aero.

"The FCS was developed by Dassault without any outside involvement. Indeed, Dassault believe that the FCS is the single most important factor influencing a pilot´s opinion of an aircraft and as such never let anybody else develop it for them."

Their first tests of optical command lines were done on a Mirage 2000 around 1983-84.

Let's note however that this option is only useful if the plane is worthy of it.
You need an unstable design with high level interactions of flight control surfaces for it
to be necessary. It would serve no purpose on a standard Cessna 172 or the likes.

Just sayin', Tay.

 

[Army research]

A I'd don't understand anything but is it yes or no for paf and also advantages and would it give our pilots an edge ?
