Item Open Access Andrew Claydon PhD(Cranfield University, 2020-11-27 10:15) Gill, Philip; Claydon, Andrew; Gaulter, Sally; Kister, GuillaumeCurrent Polymer Bonded Explosive (PBX) formulation is limited by a compromise - optimised final properties against processability. While explosive content would ideally be maximised and plasticiser content ideally minimised, the formulation would become too viscous to cast and require arduous mixing processes using conventional techniques. However, with Resonant Acoustic Mixing (RAM), formulation does not have to be constrained. Instead of mixing blades, mixing is achieved using an oscillating platform to impart acoustic pressure waves (vibrations) into the mixture. Mixing is orders of magnitude faster than conventionally achievable, and the added ability to mix in the end use casing (mixing ‘in-situ’) also renders casting obsolete in many scenarios. The research aim of the PhD is to assess how machine control and vessel design can be altered to optimise the mixing mechanism and compare material properties of composites mixed ‘in-situ’ and ‘mixed and cast’.Item Open Access Burning of DNAN-based explosive (428 mg) in a Laboratory-Scale open setup using a metal sieve to support the sample(Cranfield University, 2018-07-30 14:07) Galante, Erick; Gill, Philip; Temple, TraceyBurning of 428 mg of DNAN-based Insensitive high explosive heated from beneath, in an open setup, on a metal sieve placed on metal tray within a laboratory.Item Open Access CogShift - Typical Trial(Cranfield University, 2023-12-11 15:47) Cecotti, MarcoThis is the video of one of the vehicle trials for the CogShift project. CogShift, one of five projects which are part of an £11 million UK Government investment in autonomous vehicle research, studied driver attention and cognitive control characteristics. The project developed an optimal control-authority shifting system which takes driver attention into account.

The particular design constraints of such a motor require that the booster propellant, required to get the rocket motor up to operational speed, use the same nozzle as the sustainer propellant and as a result must have the same operational requirements such as low pressure (1.5-2 MPa compared to ~10MPa for conventional rocket motors). In simple terms, this work aims to develop an extremely high burn rate propellant which works at extremely low pressures.Item Open Access Erick Galante PhD(Cranfield University, 2018-09-13 09:14) Gill, Philip; Galante, Erick; Temple, TraceyNew safety requirements are pressuring military organizations to replace TNT with insensitive high explosives (IHEs) containing DNAN, NTO and RDX but little is known about the behaviour IHE components and formulations in the environment. The environmental impact of ordnance during the in-service phase has been studied, but most reports concern TNT-based legacy explosives and their impact on soil rather than other environmental compartments. To address this knowledge gap, IHE samples ranging from milligrams in a closed system to grams and kilograms in an open system were tested in the laboratory and field, yielding environmental impact data that helps to determine the behaviour of the materials during open burning. The prediction software HYDRUS 1D was then fed with the empirical data and the actual and predicted outcomes for the behaviour of DNAN, NTO, RDX and the IHE formulation were compared to determine whether this software can be used to predict said impacts. The thermodynamic properties of DNAN make it more likely to melt, boil and sublimate during open burning, leaving ~70% behind as unreacted residues. DNAN also inhibits the burning of RDX and NTO, such the near zero residual mass when these are burned as pure compounds increases to ~20% of the initial mass when the formulation is burned. Overall, the experiments showed that DNAN-based IHEs behave in a similar manner to TNT based legacy explosives regarding emission of greenhouse gases, but worse in terms of solid residues. Ultimately, the body of work reported through this thesis has shown that traditional open burning of DNAN-based IHE could leave as much as 12 % (w/w) of unburnt explosive on the soil. We have concluded that the open burning methodology adopted for TNT legacy munitions should be avoided for disposing of IHEs.Item Open Access Fruit and Veg vs. the Future game(Cranfield University, 2019-08-20 09:39) Hess, Tim; Craven, JoanneFruit and Veg. vs. the Future is a hybrid board / role-play game about water risks in the UK fresh fruit and vegetable system, aimed at industry stakeholders.
