> All the reverser is is a couple of hydraulically operated clamshells that close over the exhaust stream forcing it to the side rather than back. Clamshell and bucket type thrust reversal systems are one way of achieving reversal. The latter are mostly seen on low-bypass turbofans. Large high-bypass engines often use a cold-stream reversal “cascading” system that is more complicated and includes both shunting of the exhaust vector and blocking air intake into the combustion stage. You’ll see this in action on engines where the rear cowling slides backwards to uncover the cascading vanes.
