CN204965859U - Simple and easy aircraft lift experimental apparatus - Google Patents

Abstract

The utility model provides a simple and easy aircraft lift experimental apparatus, characterized by: include the base, fix pole setting and the wing model of cross -under in the pole setting on the base, the hollow body that the wing model bonded and forms for the scraps of paper, it has the through -hole that link up from top to bottom to open on the wing model. For the experiment of aircraft lift, provide homemade experimental program with low costs, easy, students just can be in and utilize current scraps of paper self -control wing model, do benefit to family's hairdryer, just can do aircraft lift and test. Be favorable to training student hands -on ability, let the student study science in playing, use the science, have very big popularization practical value.

Description

Simple and easy airplane ascensional force experimental provision

Technical field

The utility model relates to a kind of physical experiment apparatus, particularly simple and easy airplane ascensional force experimental provision.

Background technology

In prior art, the experimental provision of research aircraft lift is special complete sets of instrument, and price is more expensive, and applicable school makes lecture experiment and uses, and is unfavorable for making grouping experiment, is more unfavorable for that student goes home from manufacturing experiment.

Utility model content

For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide low, the easy self-control of a kind of cost, the convenient simple and easy airplane ascensional force experimental provision as home test.

The technical solution adopted in the utility model is: a kind of simple and easy airplane ascensional force experimental provision, it is characterized in that: comprise base, be fixed on vertical rod on base and the wing model of cross-under in vertical rod, described wing model is the bonding hollow bodies of the scraps of paper, described wing model has the through hole of up/down perforation.

Using method is: by wing model cross-under in vertical rod, hand-held family hair dryer, facing to the position on the upper side blowing of wing model, can be observed wing model to rise along vertical rod in the gas flow, show that the upper and lower surface of wing model receives to upward pressure, thus illustrate that pressure is less in flow velocity larger place.

The beneficial effects of the utility model are: be airplane ascensional force experiment, provide low, the easy homemade experimental program of cost, and students just can be in and be utilized the existing scraps of paper to make wing model by oneself, is beneficial to family's hair dryer, just can does airplane ascensional force and test.Be conducive to training student manipulative ability, study science in allowing student be at play, by science, there is very large popularization practical value.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is that the hollow scraps of paper structure of the utility model wing model splits schematic diagram;

In figure: 1 base, 2 vertical rods, 3 wing models, 4 through holes, 5 fan outlets, 6 base stock sheets, the 7 side scraps of paper, the upper surface scraps of paper.

Embodiment

As shown in Figure 1, base 1 is fixed with vertical rod 2, in vertical rod 2, cross-under has wing model 3, and wing model 3 has the through hole 4 for accommodation vertical rod 2 run through up and down, wing model 3 can slide up and down along vertical rod 2.Wing model 3 is the bonding hollow bodies of the scraps of paper.

As shown in Figure 2, the scraps of paper are cut into suitable shape, as a base stock sheet 6, two side scraps of paper 7, upper surface scraps of paper 8, then connect with adhesive tape, make hollow enclosed box body, through hole 4 is got out again with the red iron nail of burning, just make wing model 3, do vertical rod with slightly straight iron wire, do base with solid wood, or with adhesive tape, vertical rod is cemented in desk side, just can assemble package unit.

Claims (1)

1. a simple and easy airplane ascensional force experimental provision, it is characterized in that: comprise base, be fixed on vertical rod on base and the wing model of cross-under in vertical rod, described wing model is the bonding hollow bodies of the scraps of paper, described wing model has the through hole of up/down perforation.
