MTV Flare Composition

The thermochemical modelling of pyrotechnic compositions has been used as an approach to assess the quality and amount of potential combustion products [1]. However, thermochemical equilibrium calculations fail to give an exact answer to the actual species involved in dynamic processes. Thus it is necessary to take into account reaction kinetics in order to obtain a realistic insight into Magnesium/Teflon/Viton (MTV) combustion [2]. Three typical MTV formulations are given in Table 20.1. 

The initial anaerobic combustion products of these formulations at their corresponding temperature are given in Table 20.2. HF is seen to be a minor ingredient.

The operational use of MTV composition in decoy flares occurs in tactical altitudes between 500 and 10 000 m. Thus, any combustion product released into the atmosphere will undergo sufficient dilution with air before reaching the ground.
