Description of an experimental (hydrogen peroxide) rocket system and its use in measuring aileron and rudder effectiveness of a light airplane

A hydrogen peroxide fueled rocket system, which is to be used as a research tool in flight studies of stall and spin maneuvers, was installed on a light, four place general aviation airplane. The pilot controlled rocket system produces moments about either the roll or the yaw body axis to augment or oppose the aerodynamic forces and inertial moments acting on the airplane during various flight maneuvers, including the spin. These controlled moments of a known magnitude can be used in various ways to help analyze and interpret the importance of the various factors which influence airplane maneuvers. The rocket system and its installation in the airplane are described, and the results of flight rests used to measure rudder and aileron effectiveness at airspeeds above the stall are presented. These tests also serve to demonstrate the operational readiness of the rocket system for future research operations

The interest rate behaviour of bitcoin as a digital asset

Abstract: The objective of this study is to assess interest rate behaviour of bitcoin as a dig-ital asset in relation to market rates. The implied bitcoin interest rate is quantified through the assumptions of uncovered interest parity theory, and implied bitcoin exchange rate determined from the triangular of USD/BTC, and EUR/BTC. The Vector Autoregressive model is regressed on implied bitcoin interest rate along with four maturity classes of LIBOR interest rates for US and Euro markets re-spectively. The results show that there is a uni-directional impact with bitcoin interest rate responding to shocks from market rates, while shocks emanating from bitcoin to market rates are non-existent, or not statistically significant. The findings of this study have potential value towards monetary policy and capital market investors
