Direct Side Force Control Criteria for Dive Bombing. Volume 1. Summary

Abstract

A fixed base simulation study was conducted to determine design criteria for direct side force control (DFSC) when used for dive bombing. Three DSFC modes were simulated; a wings level turn and two lateral translation modes. A fixed depressed reticle bomb sight, a modified fixed sight that was roll stabilized, and a future impact point (FIP) computing sight were used. In addition, a control mode that rolled the aircraft about the bomb sight, line of sight was implemented. The simulation varied several aircraft response characteristics and control parameters to provide a large data base for analysis. Results indicate that the DSFC wings level turn mode is the best and improves pilot acceptability and his bombing accuracy over that of a conventional roll-to-turn aircraft. The pilots were able to adapt to a large range of aircraft response characteristics using the rudder pedal for DSFC inputs. No longitudinal coupling when using DSFC should exist. Pilots can tolerate a positive roll coupling when using DSFC. A lateral acceleration of about one G should be available for a combat dive bombing using DSFC.
