Aerodynamic characteristics in pitch of a series of cruciform-wing missiles with canard controls at a Mach number of 2.01

Description: From Introduction: "This paper presents the results of tests made at a Mach number of 2.01 to determine the effect of body length on the longitudinal characteristics (zero roll angle) for five complete configurations as well as for the bodies alone, the bodies plus wings, and the bodies plus canard surfaces. The experimental results are compared with some simple theoretical estimates."

China: Ballistic and Cruise Missiles

Description: This CRS report contains three parts. The first part discusses ballistic missiles of the People’s Republic of China (PRC). The second discusses the PRC’s cruise missiles. The last section offers concluding observations. Two tables summarize the discussion on current ballistic and cruise missiles in service or under development. The appendix, prepared by Robert Shuey, discusses China’s reported application of global positioning system (GPS) technology to improve the accuracy of its missiles. This report focuses on the status and current developments of China’s missile programs, rather than their history.

National Missile Defense and Early Warning Radars: Background and Issues

Description: The Clinton Administration is scheduled to decide by Fall 2000 whether the United States should begin deploying a National Missile Defense (NMD) system.This system could achieve initial operational capability by 2005 and would be designed to protect the United States from a limited attack by intercontinental ballistic missiles (ICBMs). As currently envisioned, the NMD system would operate as an integrated system that would rely on a variety of sensors to detect and track incoming missiles. One key program element is to upgrade the existing Early Warning Radars (EWR) so that they can detect and track the incoming missiles sooner. This report provides background information and technical details of these planned upgrades as well as their cost and schedule.

Longitudinal stability characteristics of a simple infrared homing missile configuration at Mach numbers of 0.7 to 1.4

Description: Report presenting the longitudinal stability characteristics of a simple infrared homing missile determined in flight with a rocket-powered model. Static and dynamic longitudinal stability derivatives of the cruciform, interdigitated, canard-wing missile configuration were determined using the pulse-rocket technique for a range of Mach numbers.

Theoretical investigation of an automatic control system with primary sensitivity to normal accelerations as used to control a supersonic canard missile configuration

Description: Report presenting a theoretical investigation of an automatic control system with primary sensitivity to normal accelerations as used to control a specific supersonic canard missile. The control system is made up of an integrating servomotor that receives a signal from an accelerometer that is sensitive to normal accelerations of the airframe that it is controlling. The acceleration control system appears to work well for obtaining longitudinal control, but works best when combined with a homing seeker or guidance system for controlling directional space.

Wind-tunnel investigation of a ram-jet missile model having a wing and canard surfaces of delta plan form with 70 degree swept leading edges: force and moment characteristics of various combinations of components at a Mach number of 1.6

Description: Report presenting testing of a ram-jet canard missile model with a wing and horizontal and vertical canard surfaces of delta plan form with 70 degree swept leading edges in the supersonic pressure tunnel. Two ram-jet nacelles were mounted in the vertical plane near the rear of the body and various combinations of components were tested. Results regarding the longitudinal and lateral characteristics, comparison with theory, and effect of nacelles on the model are presented.

Aerodynamic heating of blunt nose shapes at Mach numbers up to 14

Description: From Introduction: "The importance of blunt noses as a means of reducing the heat transfer to high velocity missiles has recently received much publicity. The question of just what blunt shape is best is still moot, and it is the purpose of this paper to present and examine some recent experimental results which may throw some light on the problem."

Iran's Ballistic Missile Programs: An Overview

Description: Iran has an active interest in developing, acquiring, and deploying a broad range of ballistic missiles. This was spotlighted in mid-July 2008 when Iran launched a number of ballistic missiles during military exercises. This report seeks to provide an overview of the reported or suspected variety of Iranian ballistic missile programs. Because there remains widespread public divergence over particulars, however, this report does not provide specificity to what Iran may or may not have, or is in the process of developing.

Analysis of low-temperature nuclear-powered ramjet missile for high altitudes

Description: From Summary: "The reactor operating conditions were varied to enable selection of values giving a good compromise between low uranium investment and loss gross weight at each altitude and flight Mach number considered. The corresponding values of reactor and missile operating conditions are presented in the report."

Transonic wind tunnel tests of the launch, jettison, and longitudinal characteristics of an airplane and missile model combination

Description: Report presenting tests of an airplane model equipped with missiles to investigate the capability of that combination to achieve satisfactory launching and jettisoning of the missiles. Information about pylon modifications, missiles in launch positions, missile trajectory, and missiles in jettison positions is provided.

A wind-tunnel investigation of the stability of the antisubmarine rocket MK 1 Mod 0

Description: Report discussing an investigation to determine the cause and provide a fix for the instability in flight of the antisubmarine rocket Mk 1 Mod 0. The Magnus effects and their nonlinear variation with angle of attack were found to affect the stability, so reducing the Magnus effects should reduce instability in the missiles. The greatest reduction of Magnus effects was found through a combination of nose-ring spoiler and the original direction of the propeller rotation, but the nose ring increased the drag.

Maneuver Performance of Interceptor Missiles

Description: From Concluding Remarks: "From these preliminary wind-tunnel tests of interceptor missile configurations and the analysis of point defense against ballistic missiles, it is concluded that adequate aerodynamic lift is readily available and should be utilized when operating under high-dynamic-pressure conditions and that more work should be done on controls, either aerodynamic or reaction type, so that the configurations may be trimmed to the angles of attack required to develop the necessary turning force."

Heat transfer and boundary-layer transition on a highly polished hemisphere-cone in free flight at Mach numbers up to 3.14 and Reynolds numbers up to 24 x 10(exp 6)

Description: From Summary: "A highly polished hemisphere-cone having a ratio of nose radius to base radius of 0.74 and a half-angle of 14.5 degrees was flight tested at Mach numbers up to 4.70. Temperature and pressure data were obtained at Mach numbers up to 3.14 and a free-stream Reynolds number of 24 x 10(exp 6) based on body diameter. The nose of the model had a surface roughness of 2 to 5 microinches as measured with an interferometer."

A torsional stiffness criterion for preventing flutter of wings of supersonic missiles

Description: From Summary: "A formula, based on a semirational analysis, is presented for estimating the torsional stiffness necessary to prevent flutter of a sweptback or unswept uniform wing that attains supersonic speeds. Results of missile flights at speeds up to Mach number 1.4 demonstrate the usefulness of the formula."
