METHOD AND DEVICE FOR MEASURING SPEED OF IMPACT AT SPORTING COMPETITIONS

摘要

FIELD: trainers. SUBSTANCE: fire sources with different intensities are ignited. Value of impact speed being necessary for quenching impact, is known for each source. Then the sources are quenched in sequence by air wave generated at impact. True speed is judged from quenched flame with maximal intensity. Device for fire quenching is made in form of a set of candles provided with impact speed indicator which is necessary to quench them. It may be also made in form of a gas burner provided with flame intensity governor. Device is also provided with the unit for measuring match of force of the flame to impact speed which is necessary for quenching the impact. EFFECT: improved precision; improved efficiency. 2 cl, 5 cl, 1 dwg
