Fairing separation mechanism, water rocket model with same and teaching aid

Abstract

The invention discloses a fairing separation mechanism, a water rocket model with the same and a teaching aid, the fairing separation mechanism comprises two groups of fairings, an accommodating cavity is formed between the two groups of fairings, a carrier plate is arranged in the accommodating cavity, and a main plate is arranged below the carrier plate; a plurality of groups of first elastic separation parts are connected between the fairing and the main plate, a plurality of groups of second elastic connection parts are connected between the carrier plate and the main plate, the first elastic separation parts and the second elastic connection parts are connected with breaking parts, and the breaking parts are fixedly connected with the main plate; and the water rocket model comprises a fairing separation mechanism, a rocket body, a parachute, an empennage, a clinker bottle and a tail jet. Separation of the fairing is guaranteed through the first elastic separation part and the second elastic connection part, the parachute is bounced and separated under the action of the second elastic connection part, it is guaranteed that the parachute can be opened in real time, and factors influencing the flight attitude and height of the rocket are explored by changing conditions.

Description

technical field [0001] The invention relates to the technical field of aerospace teaching, in particular to a fairing separation mechanism, a water rocket model with the mechanism and teaching aids. Background technique [0002] Water rockets, also known as pneumatic water-jet rockets and water-propelled rockets, are experimental devices / equipment designed using mass ratio and air pressure. The principle is to inject gas into the airtight arrow body filled with a certain amount of water, and as the air pressure in the arrow body rises, the sealing plug at the bottom is washed away, so that the water is ejected quickly and the arrow body obtains an upward thrust. It rises like a rocket and shoots out, so it is named water rocket. [0003] Water rockets are divided into products without parachute and products with parachute. At present, most of the water rocket products on the market are still without parachute. The water rocket products with parachute basically rely on gravi...

AI Technical Summary

Problems solved by technology

[0003] Water rockets are divided into products without parachute and products with parachute. At present, most of the water rocket products on the market are still without parachute. The water rocket products with parachute basically rely on gravity or automatically deploy with a timer, and it is impossible to experience the real rocket control rectification. The process of shroud separation or parachute opening
