Intelligent ignition device for machine-carried electric heating type engine of model airplane

Abstract

The invention relates to an airborne aero model electrothermal engine intelligent ignition device, which is composed of a DC / DC switch power supply module and the peripheral circuits thereof. By the improvement of the electric indexes of the switch power supply module such as the output voltage and the output current, the peripheral circuits adopt simple atypical connection method. (1) monitor and work status indicating circuits: a branch circuit composed of an ab jumper wire and a capacitance C1 between the input terminals (1, 2) of the switch power supply module; a branch circuit composed of an LED D4, a switch AN and a load R0 between the output terminals (2, 3); a branch circuit composed of an LED D3 and a silicon diode D2 and connected with the output terminal (3); and a branch circuit composed of a Schottky diode D1. (2) a resistance R2 and a potentiometer W which are in parallel connected to two ends of a resistance R3 form an output voltage regulating circuit. The invention has the advantages that: the running states of the ignition device and a glow plug are logically displayed, so the glow plug always at best work state, the persistent problem that the engine oil way and the circuits are implicated mutually is completely solved, lightweight is realized, and the ignition start of the engine is more convenient and reliable.

Description

technical field [0001] The invention belongs to the technical field of electrothermal engines in aircraft models, and in particular relates to an intelligent ignition device for airborne electrothermal engines of aircraft models. Background technique [0002] The performance of the ignition device used for the ignition and start of the electric heating engine of the aircraft model is directly related to whether the engine can start smoothly. With the advancement of technology, the ignition device of the electric heating engine of the aircraft model has gone through various forms such as manganese-zinc batteries, armor batteries, single-cell lead-acid batteries, nickel-cadmium rechargeable batteries, and series regulated power supplies. [0003] At present, the ignition device used to start the engine of the aircraft model, such as: the igniter (commonly known as: grenade) is more popular, but the built-in battery capacity of the igniter is insufficient or the performance is ...
