HSU de­vel­oped by DRDO for MBT gives bet­ter ve­hi­cle sta­bil­ity

The De­fence Re­search and De­vel­op­ment Or­gan­i­sa­tion (DRDO), un­der the Min­istry of De­fence, Gov­ern­ment of In­dia, has in­tro­duced ad­vanced Hy­dro­gas Sus­pen­sion Unit (HSU). It is a sus­pen­sion sys­tem that is in­tended for cush­ion­ing the im­pacts and shocks. It helps to keep the ve­hi­cle sta­ble when mov­ing on ir­reg­u­lar ter­rains. The sus­pen­sion is mainly for the Main Bat­tle Tanks (MBT). HSU was show­cased at the re­cent­ly­con­cluded De­fence Expo in Chen­nai.

A DRDO of­fi­cial said Auto

Com­po­nents In­dia that, “It is indige­nously de­vel­oped by our­selves. Start­ing from scratch to prod­uct re­al­i­sa­tion, the en­tire prod­uct was done by DRDO and es­pe­cially by Com­bat Ve­hi­cles Re­search and De­vel­op­ment Es­tab­lish­ment (CVRDE). This pro­vides bet­ter ride com­fort. Any ve­hi­cle needs a sus­pen­sion sys­tem, but we use 14 of such sus­pen­sions for MBT as it weighs around 70 tonne. Each of the sus­pen­sion is ca­pa­ble of sup­port­ing 5 tonne static load, 25 tonne dy­namic load and 10 tonne of steer­ing load. This en­ables the ve­hi­cle for high­speed com­bat­ing mo­bil­ity.”

MBT is a cross­coun­try ve­hi­cle with high mo­bil­ity and ride com­fort. It also holds other main char­ac­ter­is­tics like su­pe­rior firepower, high de­gree of pro­tec­tion, etc. “For this ve­hi­cle to run at a high speed, such Hydro-Gas Sus­pen­sion Unit is re­quired. With this tech­nol­ogy it pro­vides bet­ter ride com­fort and en­ables the ve­hi­cle to drive at a higher speed. Our tank is also ca­pa­ble of fire and move. This needs more sta­bil­i­sa­tion and the sus­pen­sion pro­vides it. HSU has been fit­ted into 124 tanks. We have also made a few en­hance­ments mostly on the load car­ry­ing ca­pac­ity. Ear­lier it was 50 tonne, now it can carry up to 75 tonne. We also have given it a com­pletely new de­sign,” he said.

DRDO, formed in 1958, oversees mil­i­tary’s re­search and de­vel­op­ment works. Head­quar­tered in New Delhi, DRDO was cre­ated by merg­ing the Tech­ni­cal De­vel­op­ment Es­tab­lish­ment and the Direc­torate of Tech­ni­cal De­vel­op­ment and Pro­duc­tion with the De­fence Science Or­gan­i­sa­tion. With a net­work of 52 lab­o­ra­to­ries, DRDO is en­gaged in de­vel­op­ing de­fence tech­nolo­gies cov­er­ing var­i­ous fields that in­clude aero­nau­tics, elec­tron­ics, land com­bat en­gi­neer­ing, mis­siles, and naval sys­tems. The or­gan­i­sa­tion has 5,000 sci­en­tists be­long­ing to the De­fence Re­search & De­vel­op­ment Ser­vice (DRDS) and about 25,000 other sci­en­tific, tech­ni­cal and sup­port­ing per­son­nel.
