^ Ima tu logike. Verovatno su sklapani i zato da bi se usavršili češki tehničari i inženjeri, kasnije zaduženi za njihovo održavanje.

Slican potez se koristio (i koristi se) i na nekim putnickim avionima sovjetske/ruske proizvodnje, thrust-reverser-i koji se aktiviraju pre dodira ST sa pistom.

Obrnuti potisak (skretac mlaza?) mi je razumljiv da se koristi neposredno pred dodir piste, ali otvaranje koceceg padobrana nekoliko sekundi pred dodir piste mi se cini kao glupiranje i nemarnost. Mozda gresim?

Pise vam u tekstu da je greska
Citat:Last Saturday an unusual incident took place at the Polish Air Force’s 21st Airbase in Świdwin, during the airbase’s open day. A Su-22 Fitter jet overshot the landing, and the pilot deployed the drag chute prematurely, causing the aircraft to hit the runway very hard.
It was also an unusual sight to see the jet with the chute trailing behind it, still being up in the air. This also gave the photographers and spectators at the base to witness this unique sight
Drag (or drogue) chutes are a quite common design trait of the Soviet-made jets. The system consists of a single or several parachutes placed in a special pod located in the rear section of the fuselage. The chute is ejected with the use of a smaller parachute, spring-driven or compressed air based system. After the aircraft comes to a halt, the chute is separated to prevent the aircraft from being dragged on the runway. Moreover, the chute often comes with a safety system, with a ring that breaks if the braking system is deployed at a speed which is too high. In the case above probably the speed was low enough to keep the said element intact and the chute stayed in its place.
Notably, the drag created by drogue chutes is lower than the one experienced in case of the conventional drop-parachutes in order to prevent damage to the aircraft.
The one in the video is one of the techniques used to land on a damaged runway: the chute is deployed about 7 feet above the runway and the aircraft only needs 350 meters to stop.

Iranci remontovali/modernizovali 10 Su-22
Citat:Brigadier General Hajizadeh made the announcement on the sidelines of a ceremony attended by IRGC Commander Major General Mohammad Ali Jafari, which was held in Tehran on Wednesday to deliver 10 Sukhoi Su-22 fighter jets overhauled and upgraded by domestic experts at the IRGC Aerospace Force.
With this upgrade, these bombers will be able to carry and fire smart and cluster bombs, and air-to-ground and air-to-air missiles with pinpoint accuracy, and to transfer data between drones from distances of several kilometers, the commander said.
Brigadier General Hajizadeh further stressed that in the near future, air-to-ground cruise missiles with pinpoint accuracy and a range of 1500 kilometers will be installed on the bombers.
