Abstract

A ballistic calculator, pocket sized, that when loaded with trajectory and wind drift data derived from firing tests, ballistic tables or computer predictions, will, when used in the field modify the data to give the user actual sight settings at each entry of site environmental and target orientation data requested in the display.

Description

BALLISTIC CALCULATOR
This invention relates to a ballistic calculator for marksmen
Many factors determine whether a target can be hit by a remote projectile fired from a hand held or hand supported weapon. These factors include range, temperature, air density, finng angle, wind strength and direction and dπft due to spin stabilized bodies in air
Up to now, hitting the target using such a weapon, especially at the longer ranges has been a hit or miss affair because
(a) No account is made of the vaπables, especially when moving from one venue to another
(b) Account is made of only some of the factors
(c) Some account of the factors is made by human 'guestimation'
(d) Detailed account is made by the use of complex tables which have generally fixed intervals involving time, clear thinking and extrapolation to obtain accuracy
(e) Detailed account is made by use of full sized computers, but use is limited by the fact that they cannot be taken into the field and therefore the programme input is not matched to the exact finng conditions
According to the present invention there is provided a ballistic calculator that is a pocket sized, hand held electronic unit specifically designed to provide the marksman's sight settings for elevation and azimuth (windage) in angular MILS/MOA or 'clicks' according to the input of environmental conditions and target oπentation at each finng sight
The invention consists of a method of input, a memory, an electronic micro processor and an output display The ballistic calculator is programmed using baseline data provided, input and stored from actual finng tests, computer ballistic data or ballistic tables for the particular weapon, sight and projectile to be used, at a site of known topographical and environmental conditions In the field, the micro processor calculates and displays in terms of sight settings, changes to the baseline trajectory and wind drift data as each piece of environmental or target oπentation data is asked for in the 'prompt' display and entered
Field use does not affect the stored baseline data
Each Field use setting used can be stored for future recall should it be needed
The ballistic calculator can be constructed to be used as a stand alone item, an item connected to vanous sensors for recording environmental, site and target orientation, as either above, but built into a sighting or weapon system as an integrated part of that system
A specific embodiment of the invention will now be descnbed by way of example with references to the accompanying drawing labeled Fig 1
Fig 1 shows the face of the mam panel of the calculator
Refemng to the drawing, the ballistic calculator compnses an environmentally sealed casing 1 containing the electronic circuitry micro processor, input keys, display and power service on function input key panel 2, used for loading the basic trajectory and wind ballistic data of the weapon, sight and projectile to be stored in the memory and a 'Field' numencal key panel 3 used at the firing site to input the requested environmental and target orientation information, requested in the 'Prompt' display 4, where the final sight corrections for elevation and windage will also be shown on completion of the calculations

Claims

6 A ballistic calculator, as claimed in Claim 1 , 2, 3, 4 and 5, that will automatically carry out computations to integrate drift caused by a spin stabilized projectile and show this in each readout
7 A ballistic calculator, as claimed in Claim 1 , that will record 'saved' data to memory for recall later
8 A ballistic calculator, as claimed in Claim 1 , wherein environmental gauges are built in and integrated with the microprocessor and these will include range, altitude, temperature, uphill/downhill angle and azimuth
