THE COOLNESS BEHIND THE FOURTH GENERATION FIGHTER PLANES
They are the beasts of war that have their origin in the 1980s and come as a modification of the fighter jets that reigned in the 70s. Perhaps you might have heard of the F-14s, F-15s or the F-16s common in the US military frontier. They are just a tip of the ice berg of the fourth generation variety. To be precise the models stretch as far as the modified F/A-18, F-CK-1, the Mirage 2000, J-10 and 11, HAL Tejas, JF-17, MiG-29 and the Su-27.
The 70s jet fighters were commended for their long-range missile launch abilities and could engage in fierce dogfight missile warfare given the chance. Maybe they owed their stealth performance to the relax static stability made possible by upgraded digital computers and system integration enhancements.
Enter the 80s and more advancement in computer technology saw this jets give way to the F-series of fighter jets. The avionic technology for this war jets is much different and better. They brace the AESA technology full with digital avionic buses and Infrared Search and Track systems that could smoke out enemy planes from any hide outs. Technology has gone further and has done some improvements on the Fourth generation jets. Aviation engineers brought the integrated avionics systems into the picture and made new weapon advancements as well. These special modifications saw the coming to life of the 4.5 generation jet planes.
Aircraft engineers just seem to come up with complex technology and aviation terms that boggle the mind. But if we have an overview look of the considerations they put in their technology, we might get an idea.
We can begin with the ‘fly by wire’ technology mentioned earlier that is a common feature of the 4th generation jet planes. The technology was developed to assist in aircraft aerodynamics stability. Simply put, it helps a jet plane get back to its initial altitude and position when it encounters a disturbance that makes It go off its course. It is definitely the answer to the unstableness that was associated with the jets that exhibited negative static stability. Most pilots flying these jets frowned at the ease with which the jets toppled over during turbulence encounters. The planes with positive static stability gave a breath of relief but they only maintained their altitudes all through limiting the pilot’s maneuvering ability. The fly by wire technology was the savior that merged this two to form one powerful jet with altitude flexibilities.
Another mindboggling term is the AESA, the new radar technology that comes with immovable parts and can project a much longer radar beam. The technology made the 4th generations invincible as far as quick communication between aircrafts and the control towers is concerned. The longer beam projection enables a pilot to throw signals to fellow war mates and even make a clear scan around its radar to detect enemies.
And the AESA technology had to come with another close technology known as the stealth technology. Stealth technology rendered the 4th generation jets almost invisible to enemies and could not be easily discerned among the thick clouds during warfare. One can just imagine the plight of an enemy plane when a missile flies from the blues and finishes it off!
