The invention regards a launching device for rescue parachutes for small aircraft capable of launching the parachute with adequate force for correct functioning. The power is supplied by a compressed gas stored in a gas cylinder, which is freed by a rapid release valve: the shove which the parachute receives, throws it into the air, swelling it up and this, once opened, remains connected to the aircraft by a rope. The parachute is held inside a container made up of a base which is fixed to the mobile parts of the device and of a lid which is disposed of during the release. The lid is held fast against the base by set elements whose breakage is caused by the expansion of the gas. The functioning of the device is operated by the traction of a handle which by means of a cable contained inside a sheath, frees a spring: this will push the shutter of the rapid release valve, thus letting out the pressure energy of the gas. A safety-catch is situated on the device, which joins the mobile parts to the fixed parts, thus blocking them: this safety-catch blocks the device even if this is accidently operated. The gas charge can be checked periodically by means of a gauge and the parachute easily inspected.
