The Chinese 5th Generation Fighter Has Some Truly Clever Engineering



Chinese J20 Fighter Has Clever Upgrades - Business Insider



In order to preservetheir stealthiness and keep the RCS (Radar Cross Section) as low as possible,radar-evading planes rely on weapons bay: bombs and missiles to be fired arekept inside the bays until it’s time to use them.

For instance, theF-35 can carry one AIM-120D (AIM-120C8), on a trapeze : when needed, the BVR(Beyond Visual Range) missile is lowered into the airstream on the open bombbay door, and ejected.

F-22 Raptors usecanted trapeze to put the AIM-9 Sidewinder seeked into the airstream to achievea lock on the target as the side bay doors are open.
Once the missile isfired, the bay doors close up.

Obviously, suchmethod requires the stealth plane to fly with the open bay doors for a certainamount of time, a condition that can limit the aircraft performance,maneuverability, and increases the overall plane’s RCS, with a temporaryexposure of the aircraft to the enemy radars.
Something that can bequite lethal in a Within Visual Range scenario.

The problem is to bepartly solved with the use of missiles featuring the Lock On After Launchcapability. With this kind of missile (available on the Raptor when the AIM-9Mwill be replaced by the AIM-9X Block II) the bay doors remain open just thetime it is needed to eject the missile into the airstream.

However, China mighthave found a clever solution to the problem, as the latest images of the J-20Mighty Dragon stealth fighter jet, emerging from the Chinese Internet, seem tosuggest.

Indeed, the secondprototype of the aircraft features a missile deployment device on the sideweapons bay which extracts the selected air-to-air missile and then closes thedoor to keep the reduced RCS.

Simpler and probablycheaper than the use of LOAL missiles, the J-20′s deployment device shows thatChinese engineers are not simply copying U.S. tech: if not improving it, theyare at least troubleshooting some of the issues already faced by their Americancounterparts, with some clever ideas.

great vid and animation responding to what this chap has talked about:

Look closely. You can almost see the weapon bay doors.
